Ultralong temporal coherence in optically trapped exciton-polariton condensates
نویسندگان
چکیده
We investigate an optically trapped exciton-polariton condensate and observe temporal coherence beyond 1~ns duration. Due to the reduction of spatial overlap with thermal reservoir excitons, time is more than order magnitude longer that untrapped condensate. This ultralong enables high precision spectroscopy condensate, we periodic beats field correlation function due a fine energy splitting two polarization modes Our results are important for realizing polariton simulators spinor condensates in lattice potentials.

Spatial coherence properties of one dimensional exciton-polariton condensates.
In this work, we combine a systematic experimental investigation of the power- and temperature-dependent evolution of the spatial coherence function, g^{(1)}(r), in a one dimensional exciton-polariton channel with a modern microscopic numerical theory based on a stochastic master equation approach. The spatial coherence function g^{(1)}(r) is extracted via high-precision Michelson interferometr...
متن کاملExciton-Polariton Bose-Einstein Condensates
Exciton-polaritons, mixed light-matter quasiparticles in semiconductors, have recently shown evidence for Bose-Einstein condensation. Some of the properties of condensates of exciton-polaritons are reviewed in this article. We first discuss the spontaneous appearance of long-range order and the way this can be easily accessed in the case of polariton fluids. We show that the Penrose-Onsager cri...
