Instabilities and phase Transitions in Nonequilibrium Superconductors Induced by Quasiparticle Injection
並列摘要
We use the reductive perturbation method to discuss the phase transition of the nonequilibrium superconductors induced by the injection of quasiparticles in the vicinity of the instability point Nqp~Nt. We solve the third order equation which is analogous to the time dependent Ginzburg-Landau equation exactly. We also discuss the behavior of various modes in the non-linear region for different N1 and temperature ranges. When the quasiparticle-phonon reaction is small,3/2Nc＞Nt＞Ne, we found that modes with wave number │q-qm│＜k0. and Nqp＜Nt, or modes with wave number │q-qm│＜k0 are damped, stable or unstable according to whether the initial disturbance So are less, equal to or greater than the critical disturbance Sc.
