Observation of exciton polariton condensation in a perovskite lattice at room temperature

<正>Exciton polariton are bosonic quasiparticles arising fromthe strong coupling between excitons and cavity photons.Thanks to the low effective mass inherited from their photonic components and strongly interacting bosonic nature from the constituent excitons, they are regarded as promising candidates to realize Boson-Einstein Condensation at much higher temperatures, compared with conventional atom cases.
