Abstract
We show theoretically that weak (Josephson) coupling between two localized Bose-Einstein condensates of exciton-polaritons may induce the vector polarization locking in the system. Polarization correlations between two condensates appear if the lifetime of polaritons is long enough to allow for the efficient spin relaxation. The correlations are suppressed by local effective magnetic fields originated by strain or photonic disorder.
