Superconducting State under the Influence of External Dynamic Pair Breaking

A model is developed for a superconductor under an external dynamic pair-breaking influence such as a flux of optical photons. The recombination time for quasiparticles to form pairs is much greater than the characteristic time for their thermalization to the lattice temperature $T$. For this reason the model treats the unpaired electrons as a Fermi gas at temperature $T$, but more numerous than in the complete equilibrium situation.
