Condensed matter physics and materials science form a dynamic partnership, exploring how the collective behavior of atoms gives rise to the unique properties of solids and liquids. This field bridges the gap between fundamental quantum mechanics and the practical engineering of everything from flexible electronics to superconductors, turning abstract theories into tangible innovations that shape our daily lives.
At Gist.Science, we process every new preprint in this category directly from arXiv to make these complex discoveries accessible to everyone. Our team generates both plain-language overviews and detailed technical summaries for each paper, ensuring that researchers, students, and curious minds alike can grasp the latest breakthroughs without getting lost in dense jargon.
Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
This study demonstrates that fluorination and correlated chemical disorder in biphenylene networks can actively engineer electronic transport by inducing concentration-dependent anisotropic conduction, bias-driven direction inversion, and negative differential resistance, while disorder tends to suppress these effects in favor of Ohmic behavior.
By incorporating dynamic electrostatic disorder into nonadiabatic molecular dynamics simulations using the damped shifted-force method, this study demonstrates that electrostatic interactions significantly increase reorganization energy and site energy disorder in rubrene, thereby reducing the predicted hole mobility from 35 to 21 cm² V⁻¹ s⁻¹ and achieving close agreement with experimental values.
This paper reports a comprehensive study of previously unobserved polarized infrared and terahertz photocurrents in bulk tellurium, identifying distinct mechanisms such as the photogalvanic and photon drag effects that can be distinguished by their dependence on polarization, magnetic fields, and radiation frequency, with high-frequency currents driven by direct inter-subband transitions and low-frequency currents by indirect Drude-like absorption.
This study demonstrates that using meta-GGA functionals (R2SCAN and SCAN0) instead of the standard GGA-PBE functional yields a more accurate high-pressure phase diagram for hydrogen by stabilizing molecular phases, eliminating spurious dynamical instabilities, and correcting artificial bond weakening, thereby suggesting that certain previously attributed quantum nuclear effects may actually be methodological artifacts.
This paper resolves discrepancies between continuum and ab initio models of moiré excitons by employing an atomistic Bethe-Salpeter equation framework to demonstrate that hBN encapsulation critically influences the competition between Wannier and charge-transfer characters, thereby determining the nature of the lowest-energy bright excitons in WS/WSe heterobilayers and twisted WSe homobilayers.
This study reveals that Li substitution in NaNbO3 enables a thermally driven geometric reconfiguration between coexisting polar states, which enhances the Curie temperature and induces piezoelectric hardening, establishing a general design principle for engineering ferroic properties via lattice geometry.
This paper demonstrates that the thermodynamic stability, defect energetics, and elemental mixing of inorganic solids can be unified under a simple geometric framework where a seven-faceted polyhedron in high-dimensional composition space accurately captures the behavior of diverse materials families without requiring retraining or structural input.
This study demonstrates that applying homogeneous in-plane tensile strain to MoS₂ bilayers induces a Poisson-driven contraction of the interlayer spacing, which significantly strengthens van der Waals interactions and enables the fine-tuning of terahertz interlayer breathing modes with exceptionally high Gruneisen parameters.
This paper predicts that magnetic topological materials, particularly magnetic Weyl semimetals like CoSnS, can achieve strong, broadband, and magnetic-field-free nonreciprocal thermal radiation in the infrared regime, establishing a predictive framework and quantitative design rules for next-generation thermal devices.
Through large-scale atomistic simulations, this study reveals that precipitation strengthening is not merely a result of individual dislocations cutting through or bowing around precipitates, but rather an emergent collective phenomenon driven by complex, concurrent multi-dislocation interactions that accumulate, store, and multiply across the material's microstructure.
