Complete classification of 2+1D space-time groups yields 275 crystals with novel non-symmorphic symmetries enabling chirality-selective responses and horizontal cone structures in metamaterials.
Exact asymptotic wavefunction for arbitrary spin s in the time-dependent Richardson-Gaudin model is derived independently per spin size, yielding a non-thermal steady state outside the natural GGE with mean-field exact for finite products of distinct-site spin operators.
Quasiperiodic driving of a disordered non-interacting spin-1/2 chain produces prethermal time quasicrystalline order with robust incommensurate frequency peaks, sublinear entanglement growth, and a prethermal plateau that lengthens at higher drive frequencies.
Floquet circuits can be built to host many-body cages that carry topological features and π-quasienergy modes, producing time-crystalline spatiotemporal order in models such as the quantum hard disk.
Boundary Floquet driving reconstructs bulk spectra and dynamics in non-Hermitian skin-effect systems via a new Floquet non-Bloch band theory valid at arbitrary frequencies.
Floquet strong Hilbert space fragmentation stabilizes discrete time crystals in a disorder-free kicked XXZ spin chain, with lifetime independent of frequency and exponential in system size.
Quantum jump correlations and waiting-time distributions in long-range dissipative spins display clear signatures of the paramagnetic-to-ferromagnetic transition when analyzed with tilted Lindbladian, cluster mean-field, and cumulant expansion methods.
Quantum many-body scars in a kicked long-range Ising model produce time-translation symmetry breaking via π-paired Floquet doublets, yielding period-doubling oscillations that scale to last exponentially long in system size for selected initial states.
Tuning quadrupolar interactions in a spin-1 chain reveals a conserved quantity at the SU(3) point that limits accessible states and alters quench dynamics of magnetization, entanglement, and correlations.
Semi-holographic systems with perturbative and holographic sectors exhibit prethermal time crystals through dissipationless modes in hydrodynamic channels plus short-wavelength instabilities that produce inhomogeneities over a wide temperature range.
Review of universality principles and examples in driven open quantum matter via Lindblad-Keldysh field theory, organized into three classes of nonequilibrium phenomena.
