Instability-induced formation and nonequilibrium dynamics of phase defects in polariton condensates

Liew, T. C. H.; Egorov, O. A.; Matuszewski, M.; Kyriienko, O.; Ma, X.; Ostrovskaya, E. A.


We study, theoretically and numerically, the onset and development of modulational instability in an incoherently pumped spatially homogeneous polariton condensate. Within the framework of mean-field theory, we identify regimes of modulational instability in two cases: (1) strong feedback between the condensate and reservoir, which may occur in scalar condensates, and (2) parametric scattering in the presence of polarization splitting in spinor condensates. In both cases we investigate the...[Show more]
