Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
This paper identifies common distribution shifts that hinder the generalization of Machine Learning Force Fields (MLFFs) and proposes two cost-effective, test-time refinement strategies based on spectral graph theory and auxiliary physical objectives to significantly reduce errors on out-of-distribution systems without requiring expensive ab initio labels.
This paper presents exact analytical solutions for spin-1/2 quantum clusters with Heisenberg-Kitaev interactions, revealing that the Kitaev term induces distinct thermodynamic signatures like a second Schottky anomaly and nonlinear magnetic responses, thereby offering robust experimental methods to detect these interactions in both molecular magnets and extended lattice systems.
This paper presents an exact linear-response theory that resolves the challenge of calculating Fermi-energy shifts at metallic interfaces by exploiting electronic screening to compute Fukui functions via finite electric fields, achieving sub-meV accuracy and validating the approach through work-function changes and capacitance-voltage curves.
This study establishes a rational design framework for Transition Metal Dichalcogenide (TMDC) catalysts by demonstrating that sulfur vacancies activate the inert basal planes while solid-solution alloying tunes intermediate adsorption energies, identifying (Nb,Ta)S2 as a highly selective and stable catalyst for CO2 reduction to CO.
This study demonstrates that, contrary to conventional ferroelectrics, hydrostatic pressure enhances the polarization of sliding ferroelectric bilayer boron nitride by increasing interlayer potential and charge transfer, offering a new tuning mechanism for ultrathin memory devices.
This study demonstrates that the superconductivity of noncentrosymmetric NbReSi is phonon-mediated but requires corrections beyond standard harmonic Migdal-Eliashberg theory—specifically zero-point anharmonicity and vertex corrections—to accurately reproduce its experimental transition temperature and gap.
This paper introduces the HetCat26 benchmark to evaluate fifteen general-purpose foundation machine learning interatomic potentials for heterogeneous catalysis, revealing that while current models often fail to predict adsorption and DFT site preferences despite good performance on surface energetics and reaction barriers, their transferability cannot be inferred from general materials benchmarks and is significantly hindered by inconsistencies in training data.
This paper demonstrates that field-induced crystal-field crossings in cubic Ce systems, when combined with specific strain perturbations and magnetic detuning, create a symmetry-protected framework for generating isolated diabolical points with unit Chern charge, thereby enabling synthetic topology and geometric quantum control in rare-earth materials.
This paper proposes a hydrogen-informed Rice-Beltz framework that integrates elastic interactions and transition-state theory to quantify the critical stress intensity factors for crack-tip dislocation emission under mixed-mode loading, successfully capturing the non-monotonic influence of hydrogen concentration on the ductile-to-brittle transition.
This paper reports the observation of an electronic Pomeranchuk effect in twisted bilayer MoS, where heating induces a counterintuitive transition from a conducting Fermi-liquid state to a localized generalized Wigner crystal at fractional fillings due to isospin entropy stabilization.
