英文摘要:
The electron-hole semiconductor bilayer system is one of the most promising systems to search for exciton superfluid. The exciton superfluid is metastable and will eventually decay through emitting photons. Here we show that the angle-resolved photon spectrum, momentum distribution curve, energy distribution curve, and quasiparticle excitation spectrum in the exciton superfluid show many unique and unusual features not shared by any other atomic or condensed matter systems. Observing all these salient features in the photoluminescence experiments can provide convincing evidence for exciton superfluid in electron-hole semiconductor bilayers. We also comment on relevant experimental data in both exciton and exciton-polariton systems and also suggest possible future experiments to test our theoretical predictions.
