Subhasis Sinha's Group: Self-Trapping Phenomenon, Multistability and Chaos in Open Anisotropic Dicke Dimer
Photons interacting with cold atoms in a coupled cavity system constitute an open quantum system due to its coupling with the environment. This system exhibits a plethora of fascinating
out-of-equilibrium dynamical phenomena. Such a coupled cavity system reveals a multistability phenomenon, which enables us to access different nonequilibrium phases depending on the initial
configuration. Moreover, photons can be accumulated in one of the cavities, leading to the spontaneous breaking of the symmetry between the two cavities, exhibiting self-trapping phenomena, which is robust against dissipation. Remarkably, this system can host a unique time crystalline phase, called “self-trapped time crystal”, where the photons are dynamically self-trapped. The
atom-photon chaotic dynamics can emerge within a certain parameter regime, which can shed light on the rapidly progressing area of dissipative chaos. Furthermore, chaotic motion of photons
can also coexist with self-trapped steady state, which allows us to explore chaos-assisted tunneling. Such coupled cavity system can readily be achieved in cavity and circuit QED experimental setups.
