We investigate the near-critical dynamics of atomic density fluctuations in the nonequilibrium self-organization transition of an optically driven quantum gas coupled to a single mode of a cavity. In this system cavity-mediated long-range interactions between atoms, tunable by the drive strength, lead to softening of an excitation mode recently observed in experiments. This phenomenon has previously been studied within a two-mode approximation for the collective motional degrees of freedom of…

Roton-type mode softening in a dissipative quantum many-body system with cavity-mediated long-range interactions

We report on the first experimental observation of a roton-type mode softening in a long-range interacting Bose-Einstein condensate reminiscent of the roton mode in 4He. The long-range interactions

Dynamical phase transition in the open Dicke model

In well-controlled sweeps across the Hepp–Lieb–Dicke phase transition, hysteretic dynamics showing power-law scaling with respect to the transition time suggests an interpretation in terms of a Kibble–Zurek mechanism, and indicates the possibility of universal behavior in the presence of dissipation.
