- Abstract: We show how coupling an ensemble of bistable systems to a common cavity field
affects the collective stochastic behavior of this ensemble. In particular, the
cavity provides an effective interaction between the systems, and
parametrically modifies the transition rates between the metastable states. We
predict that the cavity induces a collective phase transition at a critical
temperature which depends linearly on the number of systems. It shows up as a
spontaneous symmetry breaking where the stationary states of the bistable
system bifurcate. We observe that the transition rates slow down independently
of the phase transition, but the rate modification vanishes for alternating
signs of the system-cavity couplings, corresponding to a disordered ensemble of
dipoles. Our results are of particular relevance in polaritonic chemistry where
the presence of a cavity has been suggested to affect chemical reactions.

Phase transitions correspond to the singular behavior of physical systems in response to continuous control parameters like temperature or external fields.
Near continuous phase transitions, associated with the divergence of a correlation length, universal power-law scaling behavior with critical exponents independent of microscopic system details is found.

We investigate the impact of dephasing and the inevitable evolution into a non-Gaussian, mixed state, on the dynamics of monitored fermions.
For weak dephasing, constant monitoring preserves a weakly mixed state, which displays a robust measurement-induced phase transition.
We interpret this as a signature of gapless, classical diffusion, which is stabilized by the balanced interplay of Hamiltonian dynamics, measurements, and decoherence.

We identify a transition in the far-from-equilibrium dynamics of the system after the attractive short-range impurity-boson interaction is quenched on.
The transition should be experimentally observable via a variety of common protocols in ultracold atomic systems.
