Oscillatory dynamics of nonequilibrium dissipative exciton-polariton condensates in weak-contrast lattices
We study the nonlinear dynamics of exciton polaritons in an incoherently pumped semiconductor microcavity with an embedded weak-contrast lattice and coupled to an exciton reservoir. We elucidate fundamental features of nonequilibrium exciton-polariton condensates trapped in one-dimensional periodic potentials both in the vicinity of zero momentum (so-called ``zero-momentum state'') and at …
