Paper Abstract

The formation of half-light half-matter quasiparticle exciton polariton and its condensation in semiconductor microcavities are striking phenomena for the macroscopically quantum coherence at elevated temperature. The matter constituent of exciton polariton dictates the interacting behaviors of these bosonic particles primarily via exciton-exciton interactions. However, these interactions are all limited to the ground state exciton, although they are expected to be much stronger at Rydberg states with higher principal numbers. Here, for the first time, we observe the spontaneous formed Rydberg exciton polaritons (REPs) in a high quality Fabry-Perot cavity embedded with single crystal inorganic perovskite. Such REPs exhibit strong nonlinear behavior and anisotropic, enabling an anomalous dynamic process that leads to a coherent polariton condensate with prominent blue shift. This discovery presents a unique platform to study quantum coherent many-body physics, and enables unprecedented manipulation of these Rydberg states by new means such as chemical composition engineering, structural phase control, and external gauge fields. The solid state REP and its condensates also hold great potential for important applications, such as sensing, communication, and quantum computing.
