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. https://www.spidertattooz.com/Humboldt-Cider-Cherry-4pk-16oz-Can/
