This paper demonstrates that spin inertia, when coupled with angular-momentum-breaking interactions like pseudodipolar forces in a honeycomb ferromagnet, hybridizes precessional and nutational magnons to open topological gaps and generate chiral edge states, establishing a new route for engineering topological phases in magnetic materials.
Using molecular dynamics based on density functional theory, this study reveals that the complex high-pressure crystal phases of methane arise from the packing of specific supermolecular clusters (icosahedral and polyhedral) where a trade-off between efficient packing and suppressed rotational entropy, driven by orientation-dependent intermolecular interactions, explains the observed non-cubic symmetries and sluggish phase transitions.
This paper demonstrates that nanosecond laser doping of epitaxial boron-doped silicon achieves record-breaking carrier concentrations and lattice deformations, with the observed hyperdoping limits quantitatively explained by a combinatorial model showing that inactive dopant complexes form when neighboring substitutional sites are occupied.
This study investigates structural commonalities and differences among non-crystalline materials by analyzing Pair Distribution Functions, revealing that amorphous semiconductors exhibit similar network-forming patterns with near-zero values between their first and second peaks, whereas metallic systems display distinct features including a non-zero inter-peak value and a characteristic "elephant peak."
This study reports the successful epitaxial stabilization of magnetic GdAuSb films and GdAuSb/LaAuSb superlattices on AlO substrates, revealing their shared YPtAs crystal structure, similar electronic band structures with a rigid hole-like shift, and distinct magnetic transitions that establish a new platform for controlling magnetic and topological orders through tunable intralayer exchange and reduced dimensionality.
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 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 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.
