• Abstract: We solve a model that describes a stimulated conversion between ultracold bosonic atoms and molecules. The reaction is triggered by a linearly time-dependent transition throughout the Feshbach resonance. Our solution predicts a nonexponential dependence, with a dynamic phase transition, of the reaction efficiency on the transition rate. We find that the emerging phase can have a thermalized energy distribution with the temperature defined by the rate of the transition. This phase, however, has strong purely quantum correlations.

  We show that the presence of generic interaction between formed molecules can fundamentally alter the nature of the critical point. We find that the correlations introduced by this rather general interaction induce nontrivial many-body physics. We provide analytical and numerical descriptions of these many-body effects, along with scaling laws for the reaction yield in both the adiabatic and non-adiabatic regimes.

  A breakdown in the rotating wave approximation of the Rabi model leads to phase transition versus coupling strength. We show that the dynamics of physical quantities can reflect such a phase transition for this model.

  We study phase transitions occurring in the stationary state of the dynamics of integrable many-body non-Hermitian Hamiltonians. We observe that the entanglement phase transitions occurring in the stationary state have the same nature as that occurring in the vacuum of the non-hermitian Hamiltonian.

  The eigenstate thermalization hypothesis (ETH) offers a universal mechanism for the approach to equilibrium of closed quantum many-body systems. Here, we propose a theory-independent route to probe the full ETH in quantum simulators by observing the emergence of fluctuation-dissipation relations. Our work presents a theory-independent way to characterize thermalization in quantum simulators and paves the way to quantum simulate condensed matter pump-probe experiments.
