In open Floquet lattices the integrated left-right transmission asymmetry equals the net chirality and winding contribution of an isolated Floquet band, so the asymmetry plateau is the robust topological observable.
Proposes cavity-mediated spin-momentum-mixing to create self-ordered supersolid phases in spinor condensates, modeled by the two-component Tavis-Cummings Hamiltonian, with undamped gapless Goldstone modes.
DMRG simulations of a moiré-modulated 1D Bose-Hubbard model reveal a local supersolid phase with staggered local density order, local off-diagonal coherence, exponentially decaying global correlations, and vanishing global structure factor.
Derives and numerically validates an analog of the Lellouch-Lüscher relation linking few-body scattering loss rates to energies and widths of harmonically trapped bosonic states.
The paper experimentally demonstrates that antibunched resonance fluorescence from a single trapped atom contains time-bin-entangled photon pairs, verified by CHSH Bell inequality violation and two-photon density matrix reconstruction, with correlations vanishing beyond the antibunching timescale.
Tensor cross interpolation learns entanglement features of quantum states with polynomial samples assuming finite MPS bond dimension.
Proposes cavity-enhanced photoassociation realizing three-body interactions, leading to hybrid atom-molecule superradiance with cubic bosonic enhancement and photon-matter entanglement.
Renormalizing the Dirac field by the metric determinant and lattice regularization produces PT-symmetric Hamiltonians for static diagonal metrics and non-Hermitian dynamics with skin effect or nonunitary evolution for time- or space-dependent metrics.
DQPTs in the 1D XY model fall into six topological classes determined by the number and type (boundary or interior) of critical modes, with three classes newly identified.
Authors characterize the MBL crossover via many-body quantum metric and localization parameter, extracting a localization length from wavefunction spread measurable by the metric.
AFQMC entropy phase diagrams for the 3D Hubbard model show that interaction-dependent entropy increase and density disorder quantitatively account for the experimental AFM structure factor maximum at U/t ≃ 11.75 rather than the prior theoretical value ≃ 8.
