Abstract
The model developed by Owen and Scalapino for superconductors with excess quasiparticles at thermal equilibrium with the lattice was adapted to investigate the transport properties of the nonequilibrium superconductors. Specifically, we have calculated within this model the frequency and temperature dependence of the ultrasonic-attenuation coefficient, the dynamic electric conductivity, and the temperature dependence of the nuclear-spin relaxation time. It is found that in some cases even a small number of excess quasiparticles can change the transport property drastically.
