Exponent behavior at a dissipative phase transition of a driven Josephson junction

Abstract
Static and dynamic critical exponents and a set of spinodal exponents are calculated within a mean-field approximation for the case of a driven Josephson junction undergoing a nonequilibrium phase transition. These universal exponents obey the exponent relations obtained from scaling-for-equilibrium phase transitions. The exponents are directly related to experimental observables such as the junction voltage, its noise bandwidth, and the Josephson radiation linewidth.
