• Abstract summary: We experimentally demonstrate a self-induced Floquet system in the interacting Rydberg gas. This originates from the photoionization of thermal Rydberg gases in a static magnetic field. We probe the nonequilibrium dynamics in the bistable regime and identify the emergence of a discrete time crystalline phase.

• Abstract: Floquet systems are periodically driven systems. In this framework, the system Hamiltonian and associated spectra of interest are modified, giving rise to new quantum phases of matter and nonequilibrium dynamics without static counterparts. Here we experimentally demonstrate a self-induced Floquet system in the interacting Rydberg gas. This originates from the photoionization of thermal Rydberg gases in a static magnetic field. Importantly, by leveraging the Rydberg electromagnetically induced transparency spectrum, we probe the nonequilibrium dynamics in the bistable regime and identify the emergence of a discrete time crystalline phase. Our work fills the experimental gap in the understanding the relation of multistability and dissipative discrete time crystalline phase. In this regard, it constitutes a highly controlled platform for exploring exotic nonequilibrium physics in dissipative interacting systems.

  Time crystal, a nonequilibrium phenomenon extending spontaneous symmetry breaking into the temporal dimension, holds fundamental significance in quantum many-body physics. We numerically identify the emergence of novel nonstationary oscillatory states by analyzing the spin dynamics. This study provides many insights into the intricate interplay between the dissipation-induced spin downwards and anisotropic-interaction-induced spin precession or spin fluctuation.

  We investigate the nonequilibrium dynamics of a Josephson-coupled Jaynes-Cummings dimer in the presence of Kerr nonlinearity. Different types of transitions between the dynamical states lead to the self-trapping phenomenon. For a particular "self-trapped" state, the mutual information between the atomic qubits exhibits a direct correlation with the photon population imbalance.

We perform large-scale quantum simulations that monitor the full counting statistics of particle-number fluctuations in boson ladders. Our results suggest that large-scale fluctuations of isolated quantum systems display emergent hydrodynamic behavior.

  Floquet (periodic) driving has emerged as a powerful technique for engineering quantum systems. We report the observation of Floquet prethermalization in a strongly interacting dipolar spin ensemble in diamond. In contrast to a single-frequency drive, we find that the existence of prethermalization is extremely sensitive to the smoothness of the applied field.

• Quantum trajectories of dissipative time-crystals [0.0]
  We show that the photon count signal as well as the homodyne current allow to identify and characterize critical behavior at the time-crystal phase transition. The average time between these fluctuation events shows a power-law scaling with system size. We furthermore show that the time-integrated homodyne current can serve as a useful dynamical order parameter.
