Furthermore, in this repulsive pump regime, the addition of a running wave transverse pump gives rise to a second type of self-organization phase. We map out the rich phase diagram of the system and identify the phase transition between the two Phases as a first-order transition. The dissipated photons out of the Cavity lead to real-time access of the dynamics during the phase transition.
In our latest experiments we utilize this dissipation channel to couple the two phases and create a dynamic instability as an additional Phase. Eventually the non-stationary dynamics of the self-organized density patterns triggers a novel pumping mechanism which we present in this work.
