This paper demonstrates that giant nonvolatile magnetotransport responses in the two-dimensional antiferromagnet FePS arise from magnetoelastic reconstruction of charge transport paths along zigzag sublattice chains, enabling reconfigurable spintronic devices with exceptionally large magnetoresistance and Hall ratios.
This study establishes single-layer CrS as the first A-type antiferromagnet with a detectable Néel vector switching capability, driven by a substrate-induced magnetic moment imbalance that enables 180° rotation while maintaining air stability and a Néel temperature of approximately 160 K.
This paper proposes a model of a three-dimensional helical second-order topological superconductor constructed from coupled Rashba nanowires, which hosts gapped bulk and surface states while supporting gapless helical parafermionic hinge modes along specific boundary paths, generalizing the noninteracting Majorana hinge modes found in the limit.
This study demonstrates that vibronic coupling in hexagonal boron nitride quantum emitters causes a significant, temperature-dependent rotation of the transition dipole moment, challenging the static dipole assumption and revealing a fundamental limit for polarization fidelity in solid-state quantum networks.
This study demonstrates that the topological magneto-optical response in even-layered MnBiTe thin films can be switched between axion insulating and Chern insulating states with quantized Faraday rotation by manipulating the relative spin alignment of outermost septuple-layers, enabling thickness-dependent multilevel optical switching.
This paper demonstrates that density-density interactions can transfer bath-induced non-reciprocity to uncoupled degrees of freedom in open quantum systems, establishing the exactly solvable Hatsugai-Kohmoto model as a minimal platform for understanding interaction-mediated directional drift in both all-to-all and local interaction regimes.
This paper employs a non-Hermitian framework to identify the exceptional point as the transition between strong and weak coupling in graphene plasmon-phonon systems, demonstrating enhanced sensitivity to perturbations via coupling strength, Fermi level modulation, and incident angle variations.
This paper predicts the existence of two distinct anomalous acoustic plasmons in two-dimensional over-tilted Dirac bands, arising from unique geometric features like velocity anisotropy and open Fermi surfaces, which exhibit valley-dependent chirality and tunable dispersion.
This study predicts a sizable anomalous Hall effect in the collinear antiferromagnet CaCrO through first-principles calculations and symmetry analysis, revealing that its C-type magnetic ordering and spin-orbit coupling-induced gapped nodal lines generate significant Berry curvature despite the absence of net magnetization.
This paper demonstrates that a two-dimensional plasmonic Lieb lattice composed of graphene disks supports a quantum spin Hall analog with nontrivial topological order and helical boundary modes, driven by intrinsic next-nearest-neighbor coupling and a synthetic time-reversal symmetry.
