Multimode organic polariton lasing

In this talk I will present a beyond-mean-field approach to predict the nature of organic polariton lasing, accounting for all relevant photon modes in a planar microcavity.  Starting from a microscopic picture, I will show how lasing can switch between polaritonic states resonant with the maximal gain, and those at the bottom of the polariton dispersion. I will explain how the population of non-lasing modes can be found, and by using two-time correlations, how the photoluminescence spectrum (of both lasing and non-lasing modes) evolves with pumping and coupling strength, confirming recent experimental work on the origin of blueshift for polariton lasing.
