Figure 5
Comparison between the dynamics of the BEC of exciton–polaritons for two different initial conditions. On the top, we see the condensate distribution throughout the entire strip at an arbitrary time, long after the beginning of the simulation; on the bottom, we see the time evolution for the condensate density at \(x= 125\) \(\upmu \)m for a period of 5 ps for the system starting at (a) the steady-state solution for the unperturbed condensate, \(\varphi (x,t=0) = \sqrt{\dfrac{\gamma _{\textrm{eff}} L_y}{\Gamma }}\); and (b) the vacuum state, \(\varphi (x,t=0)=\epsilon \), with \(\epsilon \) infinitesimal.
