This paper experimentally demonstrates frequency-division multiplexing in a CoFeB magnonic waveguide, confirming that independent spin-wave channels with different frequencies can co-propagate without measurable interaction or inter-channel interference in the linear regime.
This paper employs an Ehrenfest Lagrangian approach to derive frequency-dependent electron-phonon coupling equations that incorporate nuclear-velocity corrections, demonstrating that these modifications restore all-electron sum rules and qualitatively alter vibrational responses in tight-binding and Dirac models, as validated by excellent agreement with *ab initio* calculations for gapped graphene and the Haldane model.
This paper resolves the discrepancy between the semiclassical fractional angular momentum of a 2D charge-flux composite and the strict quantization required by symmetry by demonstrating, via a full QED approach and Noether's theorem, that a gauge-invariant interaction angular momentum arising from vacuum field mediation exactly compensates for the fractional kinetic component to ensure the total angular momentum adheres to integer or half-integer quantization.
This study utilizes spectroscopic characterization and theoretical modeling to reveal that the graphene/CrSBr heterostructure induces a massive interfacial charge transfer, strain, and magnetic proximity coupling, which collectively drive an insulator-to-metal transition in CrSBr and lift spin degeneracy in graphene, establishing a versatile platform for next-generation spintronic and nanophotonic devices.
This paper theoretically predicts and characterizes a novel asymmetric antibimeron (AAB) in in-plane magnetized chiral ferromagnets with symmetry, detailing its unique structure, stabilization mechanism, coexistence properties, and current-driven dynamics to provide a roadmap for experimental observation and topological charge manipulation.
This paper demonstrates that continuous observation of electrons tunneling through a triple quantum dot system fundamentally reshapes tunneling dynamics by increasing the average occupation of the classically forbidden central dot, thereby resolving the paradox of detecting particles in virtual states through the interplay of weak localization and strong measurement-induced jumps.
Using quantum Monte Carlo simulations, this paper demonstrates that a bilayer of antiparallel dipolar excitons with a 1:2 density ratio supports a trimer superfluid phase at low temperatures and densities, which undergoes a quantum phase transition to a two-superfluid state and exhibits distinct thermal disordering pathways, with potential realization in transition metal dichalcogenide heterostructures.
By combining lattice simulations with an extended field theory analysis that incorporates one-loop renormalization of weak topological terms, this study reveals that while weak topology induces an intermediate quasi-localized phase in chiral symmetry classes, the theoretically predicted stable strong-coupling fixed point and spatially anisotropic scaling suggest that the numerically observed quasi-localized phase may be an artifact of assuming isotropic scaling in finite-size analyses.
This study demonstrates room-temperature spin injection and preservation in exciton-polaritons within a monolithic Tamm-plasmon microcavity embedding 2D halide perovskites, where rapid polariton decay outcompetes spin relaxation mechanisms to enable potential applications in chiral lasers and switches.
This study demonstrates that identifying single-photon emitters in hexagonal boron nitride using atomic-resolution ADF-STEM is fundamentally limited by sample thickness (beyond ~17 layers) and susceptible to misidentification due to residual threefold astigmatism, rendering the technique unreliable for the thicker flakes typically used in photonic research.
