This paper introduces a decoupled excitation-detection strategy using an auxiliary cavity to overcome s-SNOM limitations, enabling the direct visualization and characterization of hyperbolic whispering gallery modes with large azimuthal momentum in hexagonal boron nitride resonators.
This paper demonstrates electrically tunable orbital coupling and high-quality single-photon emission at telecom O-band wavelengths (~1300 nm) from individual InAs/InGaAs quantum dot molecules, characterized by pronounced excitonic anticrossings and a second-order correlation function of g(2)(0) = 0.017(2).
This theoretical study demonstrates that off-resonant, anisotropic optical fields can induce finite bandgaps and enable fine-tuning of spin polarizations in -wave altermagnets through second-order perturbation effects, offering significant potential for advancing spintronic applications.
This study reveals that the complex microwave response of Pauli spin blockade leakage current in p-type silicon double quantum dots arises from the interplay between spin-orbit-mediated electric dipole spin resonance and multilevel Landau-Zener interference, a phenomenon confirmed by numerical simulations and characterized by unconventional spectral features near orbital level crossings.
This paper investigates a quasiperiodically engineered diamond lattice with strand-dependent Aubry-André-Harper modulations and reveals a robust re-entrant localization-delocalization transition driven by the interplay between the modulation ratio, correlated potentials, and the lattice's intrinsic geometry.
This study reveals that in a quasiperiodic spinful antiferromagnetic Hubbard ring, electron correlations and staggered Zeeman fields drive a nonmonotonic localization evolution featuring an intermediate regime of enhanced localization and magnetic ordering, followed by a re-entrant delocalization, as consistently evidenced by multifractal analysis, diverse mean-field observables, and real-time wave-packet dynamics.
This paper theoretically predicts that the shot noise of the quantum-geometric shift current in exciton polaritons can directly measure the Quantum Fisher Information of nonclassical light, thereby revealing multiphoton entanglement that remains inaccessible to conventional photodetection.
This study demonstrates that polarization-resolved Raman spectroscopy can detect subtle, stacking-driven structural rearrangements and their associated topological phase transition in quasi-one-dimensional Bi4I4 near room temperature, even in the absence of a change in global crystallographic symmetry.
This paper reports the spatiotemporal imaging of gate-controlled multipath dynamics of fractional quantum Hall edge excitations at , demonstrating tunable trajectory switching, dispersive propagation, and long-range transverse optical responses that establish a platform for engineered nonequilibrium and analog-spacetime experiments.
This paper extends the framework of thermodynamic multipole moments from equilibrium insulators to metallic systems by establishing a direct link between Fermi-surface multipole contributions and dissipative transport, revealing that charge and spin conductivities exhibit extrema when their corresponding electric quadrupole and magnetic octupole moments vanish.
