Description
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 present
spontaneous coherence and condensation, phase singularities,
spatial ordering, and spin currents in a cold exciton gas.
