Polaritons, a growing field of condensate studies

In this talk I will review the physics of Bose condensation of polaritons, sometimes called “superfluids of light,” and review recent experimental results, such as equilibrium condensation, long-distance propagation to the global ground state of a system, phase locking of spatially separated condensates, evidence for superfluidity, measurement of correlation functions, and propagation in quasi-one-dimensional systems. I will end with a discussion of some of the challenges and promises of room-temperature condensation of polaritons.
