Abstract

We demonstrate the existence of a dynamical phase transition in the quasi-one-dimensional photonic condensate system formed in an axially symmetric optical cavity filled with a suitable thermalizing medium. The dynamical transition is observed to occur between the periodically modulated superfluid phase and the superfluid droplets phase. The parameter domains and conditions leading to such a dynamical phase transition are identified. It is observed that such a transition in the system owes its origin to the collective photon dynamics rather than thermal or quantum effects.
