This paper proposes a probabilistic protocol that entangles distant nitrogen-vacancy centers via a magnonic bus by coupling them to a non-computational transition, thereby breaking the typical tradeoff between coupling strength and entanglement fidelity to achieve near-unit fidelity even with weak coupling.
This paper presents an efficient, two-stage analytical framework based on a solvable modified Kratzer model to retrieve fundamental material parameters of monolayer transition-metal dichalcogenides directly from optical and magneto-optical exciton spectra, enabling the accurate prediction of excitonic properties without the need for numerical fitting or matrix diagonalization.
This paper proposes a minimal quantum-optical scheme using structured light to generate hybrid entanglement between photon polarization and electronic orbital angular momentum in a semiconductor quantum disk, demonstrating via master-equation analysis that a heralded single-photon emission can effectively map the electronic state to a target entangled configuration while accounting for realistic decoherence mechanisms.
This study demonstrates that in ultrathin, disordered NbN films, increasing kinetic inductance drives a crossover from conventional gap-dominated electrodynamics to a phase-fluctuation-dominated regime characterized by BKT transitions and anomalous power-law suppression of superfluid stiffness, a behavior governed by the ratio of superfluid stiffness to pairing energy and linked to nanocrystalline twin-domain disorder.
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 study demonstrates that coupling a topological insulator-based Josephson junction to a dissipative environment induces spectral bifurcation and finite lifetimes for Majorana bound states, ultimately driving an anomalous supercurrent with a non-vanishing value at zero phase difference.
