About this Research Topic
Exciton-polaritons are hybrid light-matter quasiparticles formed by strongly interacting photons and excitons (electron-hole pairs) in semiconductor microcavities. They have emerged as a robust solid-state platform for next-generation optoelectronic applications as well as for fundamental studies of non-equilibrium quantum physics.
An outstanding challenge in the context of exciton-polariton system is the method to prepare and probe the novel non-equilibrium quantum phases. Aiming at a discussion of these questions, this Research Topics includes theoretical and experimental investigations on these novel phases in exciton-polariton Bose-Einstein condensates. In particular, there is a renewed interest on the mechanisms that lead to the non-equilibrium and non-Hermitian nature of the novel phases, at both the mean-field level and beyond.
High-quality Original Research and Review articles in this field are all welcome for submission to this Research Topic. Research interests include but are not limited to the following areas:
1. Novel quantum phases in polariton Bose-Einstein condensate (BEC);
2. Non-equilibrium superfluidity;
3. Nonlinear excitations, e.g. soliton and vortex;
