This paper establishes a unified formalism for characterizing the chirality and polarization of inertial spin waves in Dzyaloshinskii-Moriya antiferromagnets, revealing how spatially nonuniform magnetic configurations and specific interaction types fundamentally alter wave degeneracy, dispersion, and handedness to advance the design of ultrafast magnonic devices.
This theoretical study demonstrates that engineered magnetic barriers in 8-Pmmn borophene enable precise, anisotropic control over electron tunneling and charge transport by leveraging the material's tilted Dirac cones to achieve directional filtering and tunable conductance.
This paper presents a compact, low-power, and thermally stable 2,048-spin bulk acoustic wave Ising machine that utilizes solid-state delay lines to achieve all-to-all connectivity and efficiently solve complex optimization problems like MAX-CUT, number partitioning, and Sudoku, outperforming both state-of-the-art optical machines and simulated algorithms in stability and specific problem-solving capabilities.
This paper proposes a scheme to extract the characteristic entropy of non-Abelian anyons in fractional quantum Hall states by inferring the charge of an antidot embedded in an interferometer through time-dependent interference phase switching, thereby overcoming the limitations of conventional equilibrium charge measurements.
This paper analyzes particle and spin currents in networks of coupled spinor exciton-polariton condensates, deriving analytical expressions for edge-resolved currents in minimal geometries and demonstrating how these currents serve as direct signatures to characterize equilibrium phases and coherence in both small plaquettes and larger rings.
This paper demonstrates that spin-orbit coupling links structural and magnetic chirality in chiral crystals to generate distinct homochiral and heterochiral -wave magnetic phases, which can be experimentally distinguished by their unique longitudinal conductivity signatures.
This paper challenges the prevailing view on topological surface states in strained, finite-width inverted-band semiconductors by demonstrating that wavefunction overlap at opposite boundaries induces backscattering that destroys state robustness, while also deriving universal boundary conditions for the Kane model that reveal a new strain-induced "wing state" absent in the Luttinger model.
This paper demonstrates that arbitrarily weak disorder can induce a topological fine structure within a trivial energy band, causing it to split into two sets of extended states with opposite Chern numbers as predicted by a localizer index, thereby revealing a previously overlooked manifestation of topology that governs a system's response to impurities beyond conventional invariants.
This paper proposes a stacking engineering strategy to construct multiferroic metals that exhibit a linear magnetoelectric effect driven by direct spin-charge interactions, a mechanism distinct from traditional insulator-based models and validated through first-principles calculations on six materials.
This paper uses dynamical phase-field simulations to reveal an unconventional, bulk-charge-driven terahertz sliding mode of domain walls in strained BaTiO membranes, offering new insights into high-frequency ferroelectric dynamics and potential applications in reconfigurable optoelectronic devices.
