The best existing methods focus on building base models that combine molecular graphs (“2D structures”) with atomic coordinates in 3D to predict molecular properties, typically through pre-training followed by fine-tuning on benchmark datasets. However, current approaches require updating the weights of the entire model during the fine-tuning procedure for each prediction task. While this enables state-of-the-art performance, it limits practical deployment, as real-world datasets are often too small to support the stable retraining of large models. Importantly, the 3D geometry of a molecule holds crucial information for predicting its properties, but a single molecular graph usually corresponds to several 3D geometries, called conformers, introducing ambiguity into the inference process. Typical solutions rely on molecular graphs, but this approach is not easily generalizable beyond organic molecules. Here, we present ConforFormer, a method that explicitly accounts for the diversity of 3D conformations of a molecule to derive a task-agnostic and conformation-agnostic vector representation. This model serves as a foundational framework, producing embeddings that can be generated once and directly applied to downstream tasks, including property prediction and structural similarity, without extensive fine-tuning.ChemRxivSat, 10 Jan 2026 00:00:00 GMThttps://dx.doi.org/10.26434/chemrxiv-2025-x68vd-v2?rft_dat=source%3Ddrss[ChemRxiv] Graph learning of sequence statistics for polymer representationhttps://dx.doi.org/10.26434/chemrxiv-2026-tb0td?rft_dat=source%3DdrssPolymers underpin critical technologies from medicine to energy, but their immense chemical and structural diversity makes rational design exceptionally difficult. Machine learning offers a way to navigate this space, yet prevailing approaches inherit small-molecule representations that fail to encode polymer-specific architecture; the distinction between random, block and other statistical copolymers is often collapsed into a categorical tag or ignored. Here, we introduce SCALE (Statistical Copolymer Architecture with Learning Edges), which recasts a copolymer as a Markovian sequence over a monomer alphabet and embeds the transition probabilities P(j/i) as edge features within a graph attention network. Message passing thus computes contextualized monomer states analogous to applying a transfer operator along the chain, while attention learns a data-driven kernel over paths that weights sequence heterogeneity versus block persistence. On a robotically synthesized, high-throughput fluorescence library, SCALE attained RMSE ≈228 and R² ≈0.84, surpassing polymer-adapted neural baselines and descriptor regressors (e.g., wDMPNN RMSE ≈326; XGBoost RMSE ≈254). The model is interpretable: edges dominate predictions for statistical (random) copolymers, whereas nodes prevail for block copolymers, consistent with NOESY 2D NMR. Beyond photophysics, SCALE generalized to antibacterial design across penta- and hexa-copolymer libraries with validation from <300 syntheses. By elevating sequence statistics to first-class learning variables, SCALE provides a generalizable, data-efficient route to closed-loop polymer discovery.ChemRxivSat, 10 Jan 2026 00:00:00

Examples include dislocation cross-slip and dislocation nucleation at interfaces and near crack tips. The stress component normal to (111) plane can strongly affect the SF energy when the stress magnitude reaches several to tens of GPa. We conduct a series of DFT calculations of SF energies in six FCC metals: Al, Ni, Cu, Ag, Au, and Pt. The results show that normal compression significantly increases the stable and unstable SF energies in all six metals, while normal tension decreases them. The SF formation is accompanied by inelastic expansion in the normal direction. The DFT calculations are compared with predictions of several representative classical and machine-learning interatomic potentials. Many potentials fail to capture the correct stress effect on the SF energy, often predicting trends opposite to the DFT calculations. Possible ways to improve the ability of potentials to represent the stress effect on SF energy are discussed.cond-mat updates on arXiv.orgMon, 12 Jan 2026 05:00:00 GMToai:arXiv.org:2601.05453v1[cond-mat updates on arXiv.org] Autonomous Discovery of the Ising Model's Critical Parameters with Reinforcement Learninghttps://arxiv.org/abs/2601.05577arXiv:2601.05577v1 Announce Type: new +Abstract: Traditional methods for determining critical parameters are often influenced by human factors. This research introduces a physics-inspired adaptive reinforcement learning framework that enables agents to autonomously interact with physical environments, simultaneously identifying both the critical temperature and various types of critical exponents in the Ising model with precision. Interestingly, our algorithm exhibits search behavior reminiscent of phase transitions, efficiently converging to target parameters regardless of initial conditions. Experimental results demonstrate that this method significantly outperforms traditional approaches, particularly in environments with strong perturbations. This study not only incorporates physical concepts into machine learning to enhance algorithm interpretability but also establishes a new paradigm for scientific exploration, transitioning from manual analysis to autonomous AI discovery.cond-mat updates on arXiv.orgMon, 12 Jan 2026 05:00:00 GMToai:arXiv.org:2601.05577v1[cond-mat updates on arXiv.org] Phase Frustration Induced Intrinsic Bose Glass in the Kitaev-Bose-Hubbard Modelhttps://arxiv.org/abs/2601.05781arXiv:2601.05781v1 Announce Type: new +Abstract: We report an intrinsic "Bubble Phase" in the two-dimensional Kitaev-Bose-Hubbard model, driven purely by phase frustration between complex hopping and anisotropic pairing. By combining Inhomogeneous Gutzwiller Mean-Field Theory with a Bogoliubov-de Gennes stability analysis augmented by a novel Energy Penalty Method, we demonstrate that this phase spontaneously fragments into coherent islands, exhibiting the hallmark Bose glass signature of finite compressibility without global superfluidity. Notably, we propose a unified framework linking disorder-driven localization to deterministic phase frustration, identifying the Bubble Phase as a pristine, disorder-free archetype of the Bose glass. Our results provide a theoretical blueprint for realizing glassy dynamics in clean quantum simulators.cond-mat updates on arXiv.orgMon, 12 Jan 2026 05:00:00 GMToai:arXiv.org:2601.05781v1[cond-mat updates on arXiv.org] A Critical Examination of Active Learning Workflows in Materials Sciencehttps://arxiv.org/abs/2601.05946arXiv:2601.05946v1 Announce Type: new +Abstract: Active learning (AL) plays a critical role in materials science, enabling applications such as the construction of machine-learning interatomic potentials for atomistic simulations and the operation of self-driving laboratories. Despite its widespread use, the reliability and effectiveness of AL workflows depend on implicit design assumptions that are rarely examined systematically. Here, we critically assess AL workflows deployed in materials science and investigate how key design choices, such as surrogate models, sampling strategies, uncertainty quantification and evaluation metrics, relate to their performance. By identifying common pitfalls and discussing practical mitigation strategies, we provide guidance to practitioners for the efficient design, assessment, and interpretation of AL workflows in materials science.cond-mat updates on arXiv.orgMon, 12 Jan 2026 05:00:00 GMToai:arXiv.org:2601.05946v1[cond-mat updates on arXiv.org] Autonomous Sampling and SHAP Interpretation of Deposition-Rates in Bipolar HiPIMShttps://arxiv.org/abs/2601.05287arXiv:2601.05287v1 Announce Type: cross +Abstract: High-power impulse magnetron sputtering (HiPIMS) offers considerable control over ion energy and flux, making it invaluable for tailoring the microstructure and properties of advanced functional coatings. However, compared to conventional sputtering techniques, HiPIMS suffers from reduced deposition rates. Many groups have begun to evaluate complex pulsing schemes to improve upon this, leveraging multi-pulse schemes (e.g. pre-ionization or bipolar pulses). Unfortunately, the increased complexity of these pulsing schemes has led to high-dimensionality parameter spaces that are prohibitive to classic design of experi-ments. In this work we evaluate bipolar HiPIMS pulses for improving deposition rates of Al and Ti sputter tar-gets. Over 3000 process conditions were collected via autonomous Bayesian sampling over a 6-dimensional parameter space. These process conditions were then interpreted using Shapley Additive Explanations (SHAP), to deconvolute complex process influences on deposition rates. This allows us to link observed var-iations in deposition rate to physical mechanisms such as back-attraction and plasma ignition. Insights gained from this approach were then used to target specific processes where the positive pulse components were expected to have the highest impact on deposition rates. However, in practice, only minimal improve-ments in deposition rate were achieved. In most cases, the positive pulse appears to be detrimental when placed immediately after the neg. pulse which we hypothesize relates to quenching of the afterglow plasma. The proposed workflow combining autonomous experimentation and interpretable machine learning is broad-ly applicable to the discovery and optimization of complex plasma processes, paving the way for physics-informed, data-driven advancements in coating technologies.cond-mat updates on arXiv.orgMon, 12 Jan 2026 05:00:00 GMToai:arXiv.org:2601.05287v1[cond-mat updates on arXiv.org] VacHopPy: A Python package for vacancy hopping analysis based on molecular dynamics simulationshttps://arxiv.org/abs/2503.23467arXiv:2503.23467v2 Announce Type: replace +Abstract: Multiscale modeling, which integrates material properties from ab initio calculations into continuum-scale simulations, is a promising strategy for optimizing semiconductor devices. However, a key challenge remains: while ab initio methods provide diffusion parameters specific to individual migration paths, continuum equations require a single effective set of parameters that captures the overall diffusion behavior. To address this issue, we present VacHopPy, an open-source Python package for vacancy hopping analysis based on molecular dynamics (MD). VacHopPy extracts an effective set of hopping parameters, including hopping distance, hopping barrier, number of effective paths, correlation factor, and attempt frequency, by statistically integrating energetic, kinetic, and geometric contributions across all paths. It also includes tools for tracking vacancy trajectories and for detecting phase transitions during MD simulations. The applicability of VacHopPy is demonstrated in three representative materials: face-centered cubic Al, rutile TiO2, and monoclinic HfO2. The extracted effective parameters reproduce temperature-dependent diffusion behavior and are in good agreement with previous experimental data. Provided in a simplified form, these parameters are well suited for continuum-scale models and remain valid over a wide temperature range spanning several hundred kelvins. Furthermore, VacHopPy inherently accounts for anisotropy in thermal vibrations, a factor often overlooked, making it suitable for simulating diffusion in complex crystals. Overall, VacHopPy establishes a robust bridge between atomic- and continuum-scale models, enabling more reliable multiscale simulationcond-mat updates on arXiv.orgMon, 12 Jan 2026 05:00:00 GMToai:arXiv.org:2503.23467v2[cond-mat updates on arXiv.org] Machine Learning Framework for Characterizing Processing-Structure Relationship in Block Copolymer Thin Filmshttps://arxiv.org/abs/2505.23064arXiv:2505.23064v2 Announce Type: replace +Abstract: The morphology of block copolymers (BCPs) critically influences material properties and applications. This work introduces a machine learning (ML)-enabled, high-throughput framework for analyzing grazing incidence small-angle X-ray scattering (GISAXS) data and atomic force microscopy (AFM) images to characterize BCP thin film morphology. A convolutional neural network was trained to classify AFM images by morphology type, achieving 97% testing accuracy. Classified images were then analyzed to extract 2D grain size measurements from the samples in a high-throughput manner. ML models were developed to predict morphological features based on processing parameters such as solvent ratio, additive type, and additive ratio. GISAXS-based properties were predicted with strong performances ($R^2$ > 0.75), while AFM-based property predictions were less accurate ($R^2$ < 0.60), likely due to the localized nature of AFM measurements compared to the bulk information captured by GISAXS. Beyond model performance, interpretability was addressed using Shapley Additive exPlanations (SHAP). SHAP analysis revealed that the additive ratio had the largest impact on morphological predictions, where additive provides the BCP chains with increased volume to rearrange into thermodynamically favorable morphologies. This interpretability helps validate model predictions and offers insight into parameter importance. Altogether, the presented framework combining high-throughput characterization and interpretable ML offers an approach to exploring and optimizing BCP thin film morphology across a broad processing landscape.cond-mat updates on arXiv.orgMon, 12 Jan 2026 05:00:00 GMToai:arXiv.org:2505.23064v2[cond-mat updates on arXiv.org] Efficient Band Structure Unfolding with Atom-centered Orbitals: General Theory and Applicationhttps://arxiv.org/abs/2506.21089arXiv:2506.21089v2 Announce Type: replace +Abstract: Band structure unfolding is a key technique for analyzing and simplifying the electronic band structure of large, internally distorted supercells that break the primitive cell's translational symmetry. In this work, we present an efficient band unfolding method for atomic orbital (AO) basis sets that explicitly accounts for both the non-orthogonality of atomic orbitals and their atom-centered nature. Unlike existing approaches that typically rely on a plane-wave representation of the (semi-)valence states, we here derive analytical expressions that recasts the primitive cell translational operator and the associated Bloch-functions in the supercell AO basis. In turn, this enables the accurate and efficient unfolding of conduction, valence, and core states in all-electron codes, as demonstrated by our implementation in the all-electron ab initio simulation package FHI-aims, which employs numeric atom-centered orbitals. We explicitly demonstrate the capability of running large-scale unfolding calculations for systems with thousands of atoms and showcase the importance of this technique for computing temperature-dependent spectral functions in strongly anharmonic materials using CuI as example.cond-mat updates on arXiv.orgMon, 12 Jan 2026 05:00:00 GMToai:arXiv.org:2506.21089v2[cond-mat updates on arXiv.org] Disordered Dynamics in High Dimensions: Connections to Random Matrices and Machine Learninghttps://arxiv.org/abs/2601.01010arXiv:2601.01010v2 Announce Type: replace +Abstract: We provide an overview of high dimensional dynamical systems driven by random matrices, focusing on applications to simple models of learning and generalization in machine learning theory. Using both cavity method arguments and path integrals, we review how the behavior of a coupled infinite dimensional system can be characterized as a stochastic process for each single site of the system. We provide a pedagogical treatment of dynamical mean field theory (DMFT), a framework that can be flexibly applied to these settings. The DMFT single site stochastic process is fully characterized by a set of (two-time) correlation and response functions. For linear time-invariant systems, we illustrate connections between random matrix resolvents and the DMFT response. We demonstrate applications of these ideas to machine learning models such as gradient flow, stochastic gradient descent on random feature models and deep linear networks in the feature learning regime trained on random data. We demonstrate how bias and variance decompositions (analysis of ensembling/bagging etc) can be computed by averaging over subsets of the DMFT noise variables. From our formalism we also investigate how linear systems driven with random non-Hermitian matrices (such as random feature models) can exhibit non-monotonic loss curves with training time, while Hermitian matrices with the matching spectra do not, highlighting a different mechanism for non-monotonicity than small eigenvalues causing instability to label noise. Lastly, we provide asymptotic descriptions of the training and test loss dynamics for randomly initialized deep linear neural networks trained in the feature learning regime with high-dimensional random data. In this case, the time translation invariance structure is lost and the hidden layer weights are characterized as spiked random matrices.cond-mat updates on arXiv.orgMon, 12 Jan 2026 05:00:00 GMToai:arXiv.org:2601.01010v2[cond-mat updates on arXiv.org] Machine learning for in-situ composition mapping in a self-driving magnetron sputtering systemhttps://arxiv.org/abs/2506.05999arXiv:2506.05999v2 Announce Type: replace-cross +Abstract: Self-driving labs (SDLs), employing automation and machine learning (ML) to accelerate experimental procedures, have enormous potential in the discovery of new materials. However, in thin film science, SDLs are mainly restricted to solution-based synthetic methods which are easier to automate but cannot access the broad chemical space of inorganic materials. This work presents an SDL based on magnetron co-sputtering. We are using combinatorial frameworks, obtaining accurate composition maps on multi-element, compositionally graded thin films. This normally requires time-consuming ex-situ analysis prone to systematic errors. We present a rapid and calibration-free in-situ, ML driven approach to produce composition maps for arbitrary source combinations and sputtering conditions. We develop a method to predict the composition distribution in a multi-element combinatorial thin film, using in-situ measurements from quartz-crystal microbalance sensors placed in a sputter chamber. For a given source, the sensor readings are learned as a function of the sputtering pressure and magnetron power, through active learning using Gaussian processes (GPs). The final GPs are combined with a geometric model of the deposition flux distribution in the chamber, which allows interpolation of the deposition rates from each source, at any position across the sample. We investigate several acquisition functions for the ML procedure. A fully Bayesian GP - BALM (Bayesian active learning MacKay) - achieved the best performance, learning the deposition rates for a single source in 10 experiments. Prediction accuracy for co-sputtering composition distributions was verified experimentally. Our framework dramatically increases throughput by avoiding the need for extensive characterisation or calibration, thus demonstrating the potential of ML-guided SDLs to accelerate materials exploration.cond-mat updates on arXiv.orgMon, 12 Jan 2026 05:00:00 GMToai:arXiv.org:2506.05999v2[ChemRxiv] ACCEL: Automated Closed-loop Co-Optimization and Experimentation Learning Enables Phase-Pure Identification in Formamidinium-based Dion–Jacobson Halide Perovskiteshttps://dx.doi.org/10.26434/chemrxiv-2026-8c93m?rft_dat=source%3DdrssSelf-driving laboratories (SDLs) are poised to transform materials discovery by integrating automation with machine learning (ML) to accelerate data-driven experimentation. However, most SDL frameworks remain limited by single-feedback optimization and lack the multi-modal diagnostics needed to resolve both optical and structural evolution in complex hybrid systems. Here, we introduce ACCEL, an automated, ML-guided closed-loop platform for identifying and synthesizing target pure phases within quasi-2D halide perovskite systems. Using a ternary 3D:2D compositional space comprising 3D FAPbI3 and two Dion–Jacobson (DJ) spacer–based components, ACCEL optimizes the 3D:2D ratios to identify compositions that converge toward a structurally and optically stable α-FAPbI3-like phase within a quasi-2D design space. Automated in-situ photoluminescence (PL) is used to monitor crystallization kinetics in real time, revealing how the relative fraction of co-spacers governs nucleation rate and phase evolution during film formation. These kinetic insights are integrated with high-throughput synthesis, automated PL analysis, and X-ray diffraction (XRD) similarity metrics within a Gaussian Process–Bayesian Optimization framework to suppress phase heterogeneity and stabilize the target phase. Rather than targeting a predefined DJ layer number, ACCEL enables optimization based on user-defined optical and structural signatures, providing a generalizable route for autonomous phase discovery in complex hybrid materials.ChemRxivMon, 12 Jan 2026 00:00:00 GMThttps://dx.doi.org/10.26434/chemrxiv-2026-8c93m?rft_dat=source%3Ddrss[ScienceDirect Publication: Joule] A critical outlook for large-scale all-solid-state batterieshttps://www.sciencedirect.com/science/article/pii/S2542435125004507?dgcid=rss_sd_all<p>Publication date: Available online 9 January 2026</p><p><b>Source:</b> Joule</p><p>Author(s): Seongjae Ko, Makoto Ue, Atsuo Yamada</p>ScienceDirect Publication: JouleSun, 11 Jan 2026 01:50:45 GMThttps://www.sciencedirect.com/science/article/pii/S2542435125004507[Wiley: Advanced Functional Materials: Table of Contents] Recycling of Thermoplastics with Machine Learning: A Reviewhttps://advanced.onlinelibrary.wiley.com/doi/10.1002/adfm.202509447?af=RAdvanced Functional Materials, Volume 36, Issue 3, 8 January 2026.Wiley: Advanced Functional Materials: Table of ContentsSat, 10 Jan 2026 15:14:36 GMT10.1002/adfm.202509447[Wiley: Advanced Functional Materials: Table of Contents] Electron Compensation Enhanced Triboelectric Sensor Assisted by Machine Learning for Tactile Perception Recognitionhttps://advanced.onlinelibrary.wiley.com/doi/10.1002/adfm.202514567?af=RAdvanced Functional Materials, Volume 36, Issue 3, 8 January 2026.Wiley: Advanced Functional Materials: Table of ContentsSat, 10 Jan 2026 15:14:36 GMT10.1002/adfm.202514567[Wiley: Angewandte Chemie International Edition: Table of Contents] Selective Ion Transport Regulation Enables High Current Density CO2‐to‐C2+ Conversion in Acidhttps://onlinelibrary.wiley.com/doi/10.1002/anie.202516139?af=RAngewandte Chemie International Edition, Volume 65, Issue 2, 9 January 2026.Wiley: Angewandte Chemie International Edition: Table of ContentsSat, 10 Jan 2026 15:07:04 GMT10.1002/anie.202516139[Wiley: Angewandte Chemie International Edition: Table of Contents] Triply Responsive Control of Ion Transport with an Artificial Channel Creates a Switchable AND to OR Logic Gatehttps://onlinelibrary.wiley.com/doi/10.1002/anie.202517444?af=RAngewandte Chemie International Edition, Volume 65, Issue 2, 9 January 2026.Wiley: Angewandte Chemie International Edition: Table of ContentsSat, 10 Jan 2026 15:04:51 GMT10.1002/anie.202517444[Wiley: Angewandte Chemie International Edition: Table of Contents] Coupled Engineering of Short‐/Long‐Range Disorder in Oxyhalides Unlocks Benchmark Sodium Superionic Conductorhttps://onlinelibrary.wiley.com/doi/10.1002/anie.202518183?af=RAngewandte Chemie International Edition, Volume 65, Issue 2, 9 January 2026.Wiley: Angewandte Chemie International Edition: Table of ContentsSat, 10 Jan 2026 15:04:51 GMT10.1002/anie.202518183[Wiley: Angewandte Chemie International Edition: Table of Contents] Atomistic Landscape of Pt Nanoparticles via Machine Learning: How Size Effect and Hydrogen Adsorption Govern Structural Ensembles and Catalytic Activityhttps://onlinelibrary.wiley.com/doi/10.1002/anie.202519209?af=RAngewandte Chemie International Edition, Volume 65, Issue 2, 9 January 2026.Wiley: Angewandte Chemie International Edition: Table of ContentsSat, 10 Jan 2026 15:04:51 GMT10.1002/anie.202519209[Wiley: Angewandte Chemie International Edition: Table of Contents] Empowering Chemistry Experts with Large Language Models for Literature Interpretation in Single‐Atom Catalysis Toward Advanced Oxidationhttps://onlinelibrary.wiley.com/doi/10.1002/anie.202520525?af=RAngewandte Chemie International Edition, Volume 65, Issue 2, 9 January 2026.Wiley: Angewandte Chemie International Edition: Table of ContentsSat, 10 Jan 2026 15:04:51 GMT10.1002/anie.202520525[Wiley: Angewandte Chemie International Edition: Table of Contents] Balancing Oxidative Stability and Ion Transport in Quasi‐Solid Polymer Electrolytes via Chlorine‐Driven Halogenation Engineeringhttps://onlinelibrary.wiley.com/doi/10.1002/anie.202521087?af=RAngewandte Chemie International Edition, Volume 65, Issue 2, 9 January 2026.Wiley: Angewandte Chemie International Edition: Table of ContentsSat, 10 Jan 2026 15:04:51 GMT10.1002/anie.202521087[Wiley: Advanced Energy Materials: Table of Contents] Machine Learning Driven High‐Throughput Screening of Asymmetric Dinuclear Cobalt for Nitrate‐to‐Ammonia Reduction with Near‐100% Selectivityhttps://advanced.onlinelibrary.wiley.com/doi/10.1002/aenm.202506009?af=RAdvanced Energy Materials, EarlyView.Wiley: Advanced Energy Materials: Table of ContentsSat, 10 Jan 2026 14:09:28 GMT10.1002/aenm.202506009[ChemRxiv] ConforFormer: representation for molecules through understanding of conformershttps://dx.doi.org/10.26434/chemrxiv-2025-x68vd-v2?rft_dat=source%3DdrssRecent years have seen a growing interest in machine learning approaches for chemical tasks. The best existing methods focus on building base models that combine molecular graphs (“2D structures”) with atomic coordinates in 3D to predict molecular properties, typically through pre-training followed by fine-tuning on benchmark datasets. However, current approaches require updating the weights of the entire model during the fine-tuning procedure for each prediction task. While this enables state-of-the-art performance, it limits practical deployment, as real-world datasets are often too small to support the stable retraining of large models. Importantly, the 3D geometry of a molecule holds crucial information for predicting its properties, but a single molecular graph usually corresponds to several 3D geometries, called conformers, introducing ambiguity into the inference process. Typical solutions rely on molecular graphs, but this approach is not easily generalizable beyond organic molecules. Here, we present ConforFormer, a method that explicitly accounts for the diversity of 3D conformations of a molecule to derive a task-agnostic and conformation-agnostic vector representation. This model serves as a foundational framework, producing embeddings that can be generated once and directly applied to downstream tasks, including property prediction and structural similarity, without extensive fine-tuning.ChemRxivSat, 10 Jan 2026 00:00:00 GMThttps://dx.doi.org/10.26434/chemrxiv-2025-x68vd-v2?rft_dat=source%3Ddrss[ChemRxiv] Graph learning of sequence statistics for polymer representationhttps://dx.doi.org/10.26434/chemrxiv-2026-tb0td?rft_dat=source%3DdrssPolymers underpin critical technologies from medicine to energy, but their immense chemical and structural diversity makes rational design exceptionally difficult. Machine learning offers a way to navigate this space, yet prevailing approaches inherit small-molecule representations that fail to encode polymer-specific architecture; the distinction between random, block and other statistical copolymers is often collapsed into a categorical tag or ignored. Here, we introduce SCALE (Statistical Copolymer Architecture with Learning Edges), which recasts a copolymer as a Markovian sequence over a monomer alphabet and embeds the transition probabilities P(j/i) as edge features within a graph attention network. Message passing thus computes contextualized monomer states analogous to applying a transfer operator along the chain, while attention learns a data-driven kernel over paths that weights sequence heterogeneity versus block persistence. On a robotically synthesized, high-throughput fluorescence library, SCALE attained RMSE ≈228 and R² ≈0.84, surpassing polymer-adapted neural baselines and descriptor regressors (e.g., wDMPNN RMSE ≈326; XGBoost RMSE ≈254). The model is interpretable: edges dominate predictions for statistical (random) copolymers, whereas nodes prevail for block copolymers, consistent with NOESY 2D NMR. Beyond photophysics, SCALE generalized to antibacterial design across penta- and hexa-copolymer libraries with validation from <300 syntheses. By elevating sequence statistics to first-class learning variables, SCALE provides a generalizable, data-efficient route to closed-loop polymer discovery.ChemRxivSat, 10 Jan 2026 00:00:00

Restricting our attention to extreme type-II multicomponent superconductors motivates focusing on the ultraclean limit. Using functional-integral techniques, we derive the Gaussian fluctuation action from which we obtain the gauge-invariant electromagnetic linear response kernel. This allows us to compute the optical conductivity tensor. We identify essential conditions required for a nonzero longitudinal conductivity at finite frequencies in a disorder-free and translationally invariant system. Specifically, this is neither related to impurity scattering nor electron-phonon interaction, but derives indirectly from the multicomponent character of the incipient superconducting order and the parent metallic state. Under these conditions, the enhancement of the DC conductivity due to fluctuations close to the critical point follows the same critical behaviour as in the diffusive limit.cond-mat updates on arXiv.orgFri, 09 Jan 2026 05:00:00 GMToai:arXiv.org:2601.04308v1[cond-mat updates on arXiv.org] Towards understanding the defect properties in the multivalent A-site Na$_{0.5}$Bi$_{0.5}$TiO$_3$-based perovskite ceramicshttps://arxiv.org/abs/2601.04725arXiv:2601.04725v1 Announce Type: new Abstract: A defect model involving cation and anion vacancies and anti-site defects is proposed that accounts for the non-stoichiometry of multi-valent $A$-site Na$_{0.5}$Bi$_{0.5}$TiO$_3$ based perovskite oxides with $ABO_3$ composition. A series of samples with varying $A$-site non-stoichiometry and $A$:$B$ ratios were prepared to investigate their electrical conductivity. The oxygen partial pressure and temperature dependent conductivities where studied with direct current (dc) and alternating current (ac) techniques, enabling to separate between ionic and electronic conduction. The Na-excess samples, regardless of the $A$:$B$ ratio, exhibit dominant ionic conductivity and $p$-type electronic conduction, with the highest total conductivity reaching $4 \times 10^{-4}$ S/cm at 450$^\circ$C. In contrast, the Bi-excess samples display more insulating characteristics and $n$-type electronic conductivity, with conductivity values within the 10$^{-8}$ S/cm range at 450$^\circ$C. These conductivity results strongly support the proposed defect model, which offers a straightforward description of defect chemistry in NBT-based ceramics and serves as a valuable guide for optimizing sample processing to achieve tailored properties.cond-mat updates on arXiv.orgFri, 09 Jan 2026 05:00:00 GMToai:arXiv.org:2601.04725v1[cond-mat updates on arXiv.org] Scalable Dielectric Tensor Predictions for Inorganic Materials using Equivariant Graph Neural Networkshttps://arxiv.org/abs/2601.04755arXiv:2601.04755v1 Announce Type: new Abstract: Accurate prediction of dielectric tensors is essential for accelerating the discovery of next-generation inorganic dielectric materials. Existing machine learning approaches, such as equivariant graph neural networks, typically rely on specially-designed network architectures to enforce O(3) equivariance. However, to preserve equivariance, these specially-designed models restrict the update of equivariant features during message passing to linear transformations or gated equivariant nonlinearities. The inability to implicitly characterize more complex nonlinear structures may reduce the predictive accuracy of the model. In this study, we introduce a frame-averaging-based approach to achieve equivariant dielectric tensor prediction. We propose GoeCTP, an O(3)-equivariant framework that predicts dielectric tensors without imposing any structural restrictions on the backbone network. We benchmark its performance against several state-of-the-art models and further employ it for large-scale virtual screening of thermodynamically stable materials from the Materials Project database. GoeCTP successfully identifies various promising candidates, such as Zr(InBr$_3$)$_2$ (band gap $E_g = 2.41$ eV, dielectric constant $\overline{\varepsilon} = 194.72$) and SeI$_2$ (anisotropy ratio $\alpha_r = 96.763$), demonstrating its accuracy and efficiency in accelerating the discovery of advanced inorganic dielectric materials.cond-mat updates on arXiv.orgFri, 09 Jan 2026 05:00:00 GMToai:arXiv.org:2601.04755v1[cond-mat updates on arXiv.org] Lateral Graphene-Metallene Interfaces at the Nanoscalehttps://arxiv.org/abs/2601.04838arXiv:2601.04838v1 Announce Type: new
