Quantum fluid effects and parametric instabilities in microcavities
Quantum fluid effects and parametric instabilities in microcavities
We present a description of the non-equilibrium properties of a microcavity polariton fluid, injected by a nearly-resonant continuous wave pump laser. In the first part, we point out the interplay between the peculiar dispersion of the Bogolubov-like polariton excitations and the onset of polariton parametric instabilities. We show how collective …
