On the remote coherence of polariton condensates in 1D microcavities: A photoluminescence study

Abstract In this review manuscript we will gather experimental evidences of the remote coherence between two polariton condensate droplets that have never overlapped in real space, examining their interference in reciprocal space. Additionally, we discuss how these interferences can be used to estimate the critical temperature for the Bose-Einstein condensate-like transition.
