Temporal coherence of spatially indirect excitons across Bose–Einstein condensation: the role of free carriers

We study the time coherence of the photoluminescence radiated by spatially indirect excitons confined in a 10 μ m electrostatic trap. Above a critical temperature of about 1 K, we show that the photoluminescence is homogeneously broadened in the dilute regime, with a spectral width around 500 μ eV t...
