This paper proposes an alternative theoretical mechanism for magnon chiral damping, demonstrating that the antisymmetric component of the Gilbert damping tensor can induce nonreciprocal spin-wave relaxation that is linear in the wave vector and significantly stronger than effects arising from Dzyaloshinskii-Moriya interactions.
This paper investigates the Casimir interaction between planar massive Dirac materials coupled to a Lorentz-violating Bumblebee-CFJ vector sector, demonstrating that repulsive regimes arise from the mixing of TE and TM bulk modes induced by the CFJ parameter rather than Hall-like conductivity, while the Dirac mass suppresses the interaction and alters its long-distance scaling.
This paper demonstrates that the curvature of a conductor-dielectric interface can induce a geometric potential that modifies the effective mass and propagation of surface plasmons, enabling their use as a platform for analogue gravity experiments, including the study of black hole quasinormal modes.
This study identifies the interplay between Landau-level mixing and ultra-short-range interactions as the microscopic mechanism that stabilizes a strongly paired composite-fermion phase, explaining the experimentally observed incompressible even-denominator fractional quantum Hall states at half-filling in graphene's lowest Landau level.
This paper demonstrates that while standard quantum point contact readout degrades the sensing advantage of interacting quantum dots by exciting them when bias exceeds the energy gap, an energy-filtered readout using a narrow-level detector preserves the superior inverse-square gap dependence of information rates, allowing interacting electron pairs to achieve significantly higher sensing performance than single electrons.
This paper theoretically demonstrates that tunable population transfer and long-lived quantum entanglement can be engineered in a two-exciton system coupled to a bimodal cavity by leveraging exchange interactions and dressed-state dynamics, with specific design rules derived for graphene nanoribbon excitons.
This paper investigates a Lorentz-covariant generalization of the Wen-Zee gauge-curvature coupling in 2+1-dimensional Maxwell-Chern-Simons gravity, demonstrating that it contributes a non-vanishing horizon boost charge to Wald entropy even when the mixed term vanishes on-shell, thereby linking quantum Hall geometric responses to gravitational thermodynamics.
This paper presents a scalable silicon quantum processor architecture that integrates STM-defined phosphorus donor-cluster arrays with optimized on-chip micromagnets to generate magnetic field gradients, thereby enabling the independent frequency-addressing of over 120 atomic spin qubits via a single microwave antenna and overcoming the bottlenecks of hyperfine interaction randomness.
This paper explores two physical consequences of the topological classification of two-dimensional free lattice Fermi seas on flat orbifolds: the emergence of anisotropic Friedel oscillations that reveal lattice symmetries in the spatial density, and a geometric correspondence linking momentum-space packing to electrical conductivity via an isoperimetric parameter.
This study combines atomic-scale monochromated EELS experiments and ab initio calculations to demonstrate that covalent bonding between the epitaxial graphene buffer layer and the SiC substrate induces site-specific orbital symmetry breaking and -state quenching, thereby modifying the material's electronic structure for potential low-energy transistor applications.
