文摘Starting from the quasiparticle and phonon kinetic equations, the order parameter equation as well as the T*μ* model, we have studied the stability of a superconducting steady state. It is shown that there are two branches of homogeneous superconducting steady states, an upper one and a lower one. Steady states on both the upper branch and the lower branch may be stable or unstable. On the basis of this result, we can explain the properties of nonequilibrium phase transitions of a superconductor under various experimental conditions.
