  The spin-orbit coupling plays an important role in the spin Hall effect and
the topological insulators. In addition, the spin-orbit coupled Bose-Einstein
condensates show remarkable quantum many-body phase transition. In this work we
tune the exciton polariton condensate by virtue of the Rashba-Dresselhaus (RD)
spin-orbit coupling in a liquid-crystal filled microcavity where perovskite
CsPbBr3 microplates act as the gain material at room temperature. We realize an
artificial gauge field on the CsPbBr3 exciton polariton condensate, which
splits the condensates with opposite spins in both momentum and real spaces.
Our work paves the way to manipulate the exciton polariton condensate with a
synthetic gauge field based on the RD spin-orbit coupling at room temperature.
