We investigate exciton-polariton condensates with a rotating potential induced by an electric field in a semiconductor microcavity ring.In the absence of transverse-electric-transverse-magnetic (TE-TM) splitting, we find that there is a critical laser pump rate, above which the quantized phase slips appear with hysteresis, and there exist quantized
