About this Research Topic
At the heart of modern physics, there are the discovery and control of new phases of matter. These are highlighted by our understanding of wholly new types of non-equilibrium quantum phases, which have no immediate counterpart in equilibrium physics.
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;
4. Spin-orbital coupling effect in polariton BEC;
5. Quantum simulation in polariton BEC.
