By combining high-resolution scanning tunneling microscopy with density functional theory, this study reveals that Fe-site ordering in the van der Waals ferromagnet FeGeTe drives nanoscale electronic phase separation, where ordered Fe(1) domains exhibit metallic behavior while deficient regions display pseudogapped states due to symmetry-allowed Fe 3d-Te 5p orbital hybridization.
This paper introduces AllScAIP, a scalable, attention-based machine-learning interatomic potential that leverages all-to-all node attention to effectively capture long-range interactions and achieve state-of-the-art accuracy across diverse molecular and material systems without relying on explicit physics-based terms.
This study employs advanced GAP interatomic potentials, molecular dynamics, and solid-state nudged elastic band calculations to elucidate the atomic-scale mechanisms and pressure-dependent nucleation barriers driving the phase transformations of silicon, particularly linking simulation results to experimental observations of hexagonal phase formation from BC8/R8 precursors.
This study employs first-principles calculations and tight-binding modeling to demonstrate that freestanding 2D honeycomb Bi, HgTe, and Al2O3-supported HgTe simultaneously exhibit first-order and higher-order topological insulator states, characterized by gapless edge and symmetry-protected corner states, with HgTe/Al2O3(0001) emerging as a particularly promising candidate for experimental realization and device applications.
This paper demonstrates a nanoscale sensing technique that utilizes a single nitrogen-vacancy center in diamond to detect and map boron vacancy defects in hexagonal boron nitride by measuring changes in spin relaxation time () caused by cross-relaxation, thereby enabling optical-free characterization of 2D spin systems beyond the diffraction limit.
Using terahertz emission spectroscopy on wedge-shaped heavy metal|Ni heterostructures, this study provides the first direct experimental evidence that orbital mean free paths in heavy metals are ultrashort (sub-nanometer scale) and shorter than spin counterparts, confirming that bulk inverse orbital Hall effect governs orbital-to-charge conversion.
This study demonstrates that the interplay between magnon-induced Brillouin light scattering and optical spin-orbit coupling enables the nonreciprocal transformation of a Gaussian beam into an optical vortex beam by simultaneously breaking temporal symmetry via magnetic ordering and spatial symmetry via light focusing, thereby revealing that magnons can control the total angular momentum of light.
This study employs first-principles calculations and Monte Carlo simulations to reveal that orthorhombic CrI exhibits a proper-screw helimagnetic ground state with out-of-plane ferroelectricity driven by interlayer sliding, where a strong magnetoelectric coupling allows for the electrical control of spin chirality in both bulk and monolayer forms via exchange-striction and spin-current mechanisms.
This paper proposes the existence of a novel interfacial topological quasiparticle called the "Janus skyrmion," which features coexisting asymmetric helicity structures at magnetic interfaces and exhibits unique one-dimensional dynamics driven by spin currents and thermal fluctuations without the skyrmion Hall effect.
This paper presents a noise-cancellation method that generalizes techniques from piezoelectric coupling to accurately compute finite-temperature elastic constants across diverse crystalline and disordered systems by evaluating stress differences between identically thermostatted strained and unstrained simulations.
