The effect of nonequilibrium fluctuations on coupled phase oscillators is studied in a basic model. Its extremely rich behavior, including first and second order phase transitions, time-periodic phases, multiple anomalous hystereses, negative mobility, and other remarkable response properties, is unraveled by both analytical and numerical calculations.
