This paper demonstrates that a low-energy Kondo model on a triangular lattice with nested Fermi surfaces at and points naturally stabilizes robust non-coplanar chiral magnetic orders, which can induce a quantized quantum anomalous Hall effect with without relying on specific tight-binding details.
This paper establishes a theoretical framework connecting the electromagnetic sector of the Standard-Model Extension (SME) for Lorentz violation with crystallography, demonstrating how crystal symmetries parametrize optical media properties and enabling the use of specific materials as condensed-matter analogs to rediscover and propose novel optical effects.
This paper presents a unified Green's-function theory demonstrating how charge-density-wave fluctuations attenuate acoustic phonons through distinct local-intensity and texture scattering channels, successfully explaining experimental observations of phonon softening and anomalous thermal transport in various correlated materials like 2H-TaSe.
This paper proposes a novel mechanism for magnetoresistance driven by quantum decoherence across the entire Fermi sea rather than conventional momentum relaxation, revealing a linear dependence on impurity density and complex temperature behaviors that offer a new electrical probe for decoherence phenomena.
This paper investigates a transverse field Ising chain with non-Hermitian Gamma interaction, demonstrating that parity-time symmetry breaking induces a gapless phase with long-range and dynamical spin-nematic order, thereby revealing a rich quantum phase diagram and offering a scheme for generating such order through non-equilibrium dynamics.
This paper demonstrates that coupling a magnetic Josephson junction to a dissipative environment induces spin-dependent broadening of Andreev levels, which shifts the transition to higher magnetic fields and enables its control via the relative angle between the external field and reservoir magnetization, thereby establishing non-Hermiticity as a novel resource for engineering superconducting current-phase relations.
This study theoretically and numerically demonstrates the generation, nonlinear propagation, and potential application of topologically trivial magnetic solitons in ferromagnetic nanowires for the discrete, digital manipulation of domain walls in spintronic devices.
This paper introduces a unified framework and a new dimensionless parameter, , to characterize how variations in inter-sublattice exchange coupling govern the stability and configuration of ferrimagnetic skyrmions, revealing a transition from strong-coupling regimes where DMI-free skyrmions can be stabilized to weak-coupling regimes where standard effective models fail.
This paper demonstrates that asymmetric impurity scattering, when coupled with the anomalous spin polarizability of Bloch electrons, generates a significant extrinsic contribution to Neel spin-orbit torque in antiferromagnets like CuMnAs, offering a new band-geometry-driven mechanism for efficient electrical control.
This paper introduces a Davies-Morris-Shore framework for interacting multilevel quantum batteries, demonstrating that two coupled qutrits can utilize exchange interactions and anharmonicity to generate robust dark and funnel states that enable long-lived energy storage by directing decay into protected manifolds.
