Spectral graph analysis of the Hilbert-space connectivity graph detects exact fragmentation and nearly fragmented sectors with slow leakage in the t-J model and Hubbard chain.
Graph-energy centrality applied to Fock-space graphs captures weak ergodicity-breaking transitions in quantum many-body systems and scales to hundreds of sites or the thermodynamic limit.
Experimental realization of large-scale U(1) quantum spin liquid regions in a 2D analog quantum simulator using ultracold atoms, with evidence from Gauss-law compliance, pinch-point correlations, and many-body coherence over ~100 sites.
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.
Dynamical quantum phase transitions in the reduced Loschmidt echo persist under purely gain or loss dissipation but are completely smeared by any combination of both channels, even when one is infinitesimal.
Rydberg arrays realize Ising criticality with E8 mass spectra in chains and first signatures of D8^(1)-organized bound states from interchain confinement in ladders.
In a monitored dissipative spin model realizable on Rydberg simulators, free-energy functionals applied to trajectory ensembles identify dynamical features akin to hydrophobic effects in classical phase transitions.
Hardware-efficient protocol for measuring complex Loschmidt echoes in a Fermi-Hubbard optical-lattice processor via quench dynamics and tailored imaginary-time pulses.
Operator Loschmidt echoes in noisy unitary dynamics are equivalent to the norm of dissipative dynamics after noise averaging, exhibiting Gaussian decay for pt ≪ 1 and noise-independent exponential decay for pt ≫ 1, with exact results proven in the dissipative random phase model.
The paper reviews advances in quantum simulation of out-of-equilibrium dynamics in gauge theories, covering particle production, string breaking, thermalization, and related phenomena.
