Amplitude-mode dynamics of polariton condensates
(2011)We study the stability of collective amplitude excitations in nonequilibrium polariton condensates. These excitations correspond to renormalized upper polaritons and to the collective amplitude modes of atomic gases and ... -
Condensation and lasing of microcavity polaritons: comparison between two models
(Elsevier, 2005)Condensation of microcavity polaritons and the substantial influence of pair-breaking disorder and decoherence leading to a laser regime has been recently considered using two different models: a model for direct two ... -
Polariton condensation with localized excitons and propagating photons
(American Physical Society, 2004)We estimate the condensation temperature for microcavity polaritons, allowing for their internal structure. We consider polaritons formed from localized excitons in a planar microcavity, using a generalized Dicke model. ...
