Sommaire:

An indirect exciton is a bound pair of an electron and a hole confined in spatially separated layers. Due to their long lifetimes, indirect excitons can cool down below the temperature of quantum degeneracy. This gives an opportunity to study cold exciton gases.
We will overview experimental studies of spontaneous coherence and condensation, phase singularities, spatial ordering, and spin textures in a cold exciton gas.
