This paper presents a semiclassical spin dynamics framework for computing thermal Hall conductivity via linear response theory, demonstrating its effectiveness in capturing non-linear magnon interaction effects in chiral ferromagnets and Kitaev magnets beyond simple non-interacting approximations.
This paper reviews and clarifies the validity of Pfaffian-based topological invariants in one-dimensional semiconductor-superconductor nanowires by demonstrating their equivalence across momentum-space, real-space, and disordered systems, while establishing a direct physical interpretation linking the invariant to ground-state fermion parity.
This paper provides experimental evidence for intrinsic, spin-polarized superconductivity in mesoscopic Fe(Te,Se) rings, characterized by a current-dependent magnetic field and dual flux quantization that is explained by a model combining Rashba coupling with anisotropic out-of-plane interactions.
This paper investigates the quantum dynamics of two repulsively interacting particles confined to a helix, revealing how the helix's geometry creates a tunable multi-well potential that governs complex wave packet scattering patterns, including beats and pulsed emissions.
This study introduces ultralight, three-dimensional "bird's-nest" scaffolds made from FeCoNiCrCu high-entropy alloy nanowires that achieve metal-like thermal and magnetic functionality at less than 1% of bulk density by co-engineering configurational entropy with structural porosity.
Using scanning tunneling microscopy and tight-binding calculations, this study reveals how strain induces distinct domain wall transitions and modulates electronic states in marginally twisted bilayer graphene, establishing strain as a key control parameter for its structural and electronic properties.
This paper investigates the orbital-Zeeman cross correlation in altermagnets, revealing that while -wave order parameters have limited or magnitude-reducing effects on Rashba metals and topological insulator surfaces, -wave order parameters induce a sign change in Rashba metals and preserve the chemical potential jump magnitude in topological insulators while reducing the overall term.
This paper proposes and numerically verifies a lattice formulation of the -valued Arf-Brown-Kervaire invariant for Majorana fermions on two-dimensional non-oriented manifolds, demonstrating that it can be extracted from Pfaffians of the Wilson Dirac operator and agrees with continuum theory results.
This study utilizes first-principles calculations and a coupled-Dirac-cone model to demonstrate that the topological nature and magneto-optical response of five-septuple-layer MnBiTe films are tunable and can switch between topological and trivial states depending on the relative spin orientations of the surface layers.
This paper proposes metal-organic frameworks (MOFs) as a versatile, designable platform for realizing the nonlinear Hall effect by mapping their electronic structures to a universal low-energy model where symmetry-breaking mechanisms generate Berry-curvature hotspots near the Fermi level.
