| contents | We propose a grated microcavity setup to form trapped polariton condensates with parity-time ($\mathcal{PT}$) symmetry and study their polarization dynamics. The pseudo-conservative dynamics of the Stokes vector in proposed configuration is preserved in the presence of polariton-polariton interaction. In the case of weak gain-dissipation inbalance, as compared to the linear polarization splitting, the polarization Stokes spheres are deformed into ellipsoids. When linear polarization splitting becomes weak, i.e., when $\mathcal{PT}$-symmetry is broken for noninteracting system, the Stokes spheres are transformed into hyperboloids, but the dynamics is still described by closed trajectories, allowing manipulation of the polarization of polariton condensate by changing polarization splitting without losing its coherency. |
