Phase diagram and universal scaling regimes of two-dimensional exciton-polariton Bose-Einstein condensates

This repository contains all the datas and documentation required to reproduce the figures of this article, in which we investigate the phase diagram and universal scaling regimes of a two dimensional exciton-polariton Bose-Einstein condensate. The condensates dynamics is described by a generalized Gross-Pitaevskii equation (gGPE) coupled to an exciton reservoir, which we solve in space and time for different values of the blueshift at threshold. In doing so, we are able to adjust the effective nonlinearity of the condensate phase across a broad range of values, and identify three different universal regime in the nonequilibrium stationary state of the condensate: the Edwards-Wilkinson regime, the Kardar-Parisi-Zhang regime, and a vortex dominated regime. All these documents as well as a small tutorial are available following this gitlab link.
