Structured-light-mediated hybrid entanglement between photon polarization and electronic orbital angular momentum

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.

Power-Law Suppression of Superfluid Stiffness in High-Kinetic-Inductance NbN Films

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.

Frequency-dependent electron-phonon coupling and vibrational responses in tight-binding and continuous Dirac models with nuclear velocity correction

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.

Angular Momentum Quantization of a Charge-flux Composite: Quantum Electrodynamic Approach

This paper resolves the discrepancy between the semiclassical fractional angular momentum of a 2D charge-flux composite and the strict quantization required by O(2)O(2) 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.

Proximity-induced charge transfer, strain and magnetic exchange in graphene/CrSBr heterostructure

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.

Capturing an Electron in the Virtual State

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.

Trimer superfluidity of antiparallel dipolar excitons in a bilayer heterostructure

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.

Simulational and theoretical studies of the Anderson transition in the chiral symmetry classes with weak topology

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.
