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.

光学腔中光子冷凝物的动态相变

我们证明了在充满适当热介质的轴对称光学腔中形成的准一维光子冷凝系统中存在动态相变。观察到动态过渡发生在周期性调制的超流体相和超流体液滴相之间。确定导致这种动态相变的参数域和条件。可以观察到，系统中的这种转变起因于集体光子动力学，而非热效应或量子效应。
