Thermal Decoherence of a Nonequilibrium Polariton Fluid
Thermal Decoherence of a Nonequilibrium Polariton Fluid
Exciton polaritons constitute a unique realization of a quantum fluid interacting with its environment. Using selenide-based microcavities, we exploit this feature to warm up a polariton condensate in a controlled way and monitor its spatial coherence. We determine directly the amount of heat picked up by the condensate by measuring …
