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 paper employs oriented spin group theory and spin-orbit-coupling tensor expansion to reveal that altermagnets with fourfold rotation symmetry connecting opposite-spin sublattices exhibit distinct orbital and spin magnetization orders, leading to a coaxial Hall effect that enables deterministic switching of the Néel order for high-performance, stray-field-free spintronics.
This paper establishes the theoretical connection between topological charge, helicity, and vorticity in type-II multiferroics by introducing a reverse spin-current model that demonstrates the mutual influence between electric polarization and spin evolution as a requirement for the conservation of these topological invariants.
This paper demonstrates that symmetry-enforced chiral phonons and associated anomalous Nernst responses can emerge in zero-field altermagnets like CrSb through relativistic magnon-phonon coupling, which imprints altermagnetic -wave symmetry onto phonon angular momentum despite the system's compensated magnetic ground state.
Using a bipolar random Anderson model, this study reveals that antisite defects in doped FeVAl Heusler alloys simultaneously enhance local magnetic moments in -type and suppress them in -type compounds, thereby elucidating the critical role of these defects in governing magneto-thermoelectric functionalities.
This first-principles study predicts that the MCN family (M = Ag, Au, Cu) exhibits rare negative and zero linear compressibility across all six members due to extreme elastic anisotropy arising from a unique "bamboo forest" geometry, while also identifying previously unreported crystal phases for AgCN, CuCN, and AuCN.
This study demonstrates that the insulating behavior observed on the surface of metallic bulk 1T-TaSe arises from a thermodynamically favored charge-density-wave stacking reconstruction that opens a band gap via interlayer orbital hybridization, rather than from the previously assumed surface Mott physics driven by electron correlations.
This study demonstrates that employing modified Hartree-Fock pseudopotentials for copper core electrons while retaining (semi-)local functionals for valence electrons eliminates propagated density errors, thereby achieving simultaneous high accuracy in both bandgaps and lattice constants for over 50 closed-shell copper semiconductors.
This paper introduces a modified Moss rule based on the optical absorption edge to identify underexplored high-refractive-index materials, revealing that the (Hf,Zr)2(S,Se)N2 chalconitride family offers superior optical properties compared to state-of-the-art TiO2 and SiC for next-generation photonic applications.
Using ultrafast coherent phonon spectroscopy across a wide temperature range, researchers identified that while high-frequency optical phonon modes in T-WTe follow conventional anharmonic scattering, the low-frequency 2.4 THz mode exhibits anomalous behavior attributed to phonon-electron scattering.
This study reveals that the electronic structure of the Sb/Au(111) surface in the Rec phase is governed by the interplay between reconstruction-induced Umklapp scattering, which creates folded Fermi pockets, and significant Sb-Au orbital hybridization that modifies the underlying Au-derived bands.
