Abstract:
That excitons in solids might condense into a phase-coherent ground
state was proposed about 40 years ago, and has been attracting experimental and
theoretical attention ever since. Although experimental confirmation has been
hard to come by, the concepts released by this phenomenon have been widely
influential. This tutorial review discusses general aspects of the theory of exciton
and polariton condensates, focussing on the reasons for coherence in the ground
state wavefunction, the BCS to Bose crossover(s) for excitons and for polaritons,
and the relationship of the coherent condensates to standard lasers.
