Abstract
There have been extensive experimental search for possible exciton superfluid in semiconductor electron-hole bilayer systems below liquid Helium temperature. However, exciton superfluid are meta-stable and will eventually decay through emitting photons. Here we show that the light emitted from the excitonic superfluid has unique and unusual features not shared by any other atomic or condensed matter systems. We evaluate angle resolved photon spectrum, momentum distribution curve, energy distribution curve and quasiparticle excitation spectrum in the exciton superfluid and comment on relevant experimental data in both exciton and exciton-polariton systems.
