This paper reveals a mechanism for an unconventional anomalous Hall effect in metallic spin-spiral systems, where the interplay of spin-orbit coupling, magnetization, and helical plane orientation generates odd-parity spin splitting and Berry curvature near gapped spin-nodal lines.
This paper reports the emergence of an in-plane anomalous Hall effect and a pronounced third-harmonic Hall response in an easy-plane trigonal magnet, demonstrating that reducing magnetic anisotropy enhances a symmetry-governed, intrinsic nonlinear transport mechanism characterized by a cubic field dependence and a dominant sin(3θ) angular component.
This paper investigates charged soliton branches (Q-balls) in quasi-one-dimensional chiral magnetic systems by comparing antiferromagnetic and ferromagnetic dynamical models, revealing how their distinct time-evolution mechanisms—specifically second-order derivatives versus Berry-phase dynamics—lead to fundamentally different existence conditions, frequency windows, and stability criteria for these magnetic droplets despite sharing the same static energy functional.
This study reveals that the pronounced resistivity anomaly observed in the antiferromagnetic compound EuZn2As2 near its Néel temperature arises from spin-scattering mechanisms rather than a reconstruction of the electronic structure, as evidenced by the minimal temperature-dependent changes in its band structure observed via ARPES and DFT calculations.
This paper proposes a novel method to enhance magnonic frequency comb generation by leveraging the intrinsic geometric nonlinearity of the magnetization vector, which, through transverse Floquet engineering, converts a transverse drive into a longitudinal parametric modulation to achieve low-threshold, high-flatness comb generation in the linear regime.
This paper theoretically demonstrates that a lateral WS2-MoS2-WS2 double heterojunction supports electrically switchable one-dimensional excitons, where an external electric field continuously transforms a zero-dipole, quadrupolar ground state into a dipolar state, enabling geometric control over the system's Stark sensitivity.
This paper proposes a quantum-enhanced paradigm for axion dark matter detection that utilizes an interferometric protocol with non-linear cavities and gyromagnetic modes to directly measure axion amplitude and phase, promising significant improvements in sensitivity and mass scanning range compared to standard haloscopes.
Through large-scale Monte Carlo simulations of the classical 2D Heisenberg model, this study reveals that finite-temperature phase transitions across different spin-symmetry regimes are governed by the interplay between finite-size effects and vortex-antivortex pair proliferation, clarifying how characteristic temperatures deviate from standard BKT theory and evolve with magnetic anisotropy and system size.
This paper develops a comparative analytical framework using compact electro-thermal models to elucidate the fundamental physical mechanisms behind the enhanced performance and scalability of disc-type phase-change memory for analog in-memory computing applications.
This paper presents a resilient, strain-mediated antiferromagnetic MnIr/PMN-PT bare-die processor that enables high-accuracy, ultra-low-energy analog computing for autonomous intelligence in extreme environments characterized by high temperatures, intense magnetic fields, and radiation.
