• Abstract: We investigate the adiabatic evolution of thermal state in non-reciprocal many-body systems coupled to their environment and subject to periodic drivings. In such systems we show that besides the dynamical phase a geometrical phase can exist and it drives the relaxation dynamic of the system. On the contrary to the dynamical phase which always pushes the system toward its equilibrium state we show that the geometric phase can speed up or reduce the speed of relaxation process. These results could have applications in the field of thermal management of complex systems.

  We investigate the spatial aspect of thermalization in quantum many-body systems. We uncover a two-stage thermalization process along the spatial dimension. We argue that similar prethermal chaotic phases are likely to occur in a broad range of extended driven-dissipative systems.

  Environments in quantum thermodynamics usually take the role of heat baths. We show that within the same model, the environment can take three different thermodynamic roles. The exact role of the environment is determined by the strength and structure of the coupling.

• Emergent symmetries in prethermal phases of periodically driven quantum systems [0.0]
  Periodically driven closed quantum systems are expected to eventually heat up to infinite temperature reaching a steady state. However, their properties in long prethermal regimes are qualitatively different from that in their infinite temperature steady states. These, often experimentally relevant, prethermal regimes host a wide range of phenomena. They may exhibit dynamical localization and freezing, host Floquet scars, display signatures of Hilbert space fragmentation, and exhibit time crystalline phases.

• System-bath entanglement during Markovian relaxation of a fermionic impurity [0.0]
  We show that transient entanglement can be observed even in the weak coupling regime. This entanglement vanishes for long times, but is preserved over timescales comparable to the relaxation time. We relate the presence of such transient entanglement to the unitary character of the system-bath dynamics underlying the reduced Markovian description.

• Low-energy prethermal phase and crossover to thermalization in nonlinear kicked rotors [0.0]
  We show that when the random kinetic energy is smaller than the interaction energy, this system exhibits a much richer dynamical phase diagram. We develop a hydrodynamic theory of this phase and find a very good agreement with exact numerical simulations. We explore the full dynamical phase diagram of the system and find that the transition toward full thermalization is characterized by relatively sharp crossovers.

  We find the diffusive transport of fluctuation in the prethermal regime. We attribute non-diffusive and non-localize structure of correlation to the crossover regime. We exploit the statistical unrelated nature of the angles of the rotors in the heating regime to find the analytical form of the correlator.

  We quantum-simulate the reheating-like dynamics of a generic cosmological single-field model in an ultracold Bose gas. Expanding spacetime as well as the background oscillating inflaton field are mimicked in the non-relativistic limit. The proposed experiment has the potential of exploring the evolution up to late times even beyond the weak coupling regime.
