Abstract :

I report the first study for the impact of the applied electric field on the Cooper pairs prior the superconductivity. The generalized Maxwell equations are obtained from time-dependent Ginzburg-Landau theory using the first-order formalism in gauge theory. This formalism is very useful but not popular among solid-state physicists. This is why I gave more details in the derivation. The results give new insight for the electrodynamics of s-wave superconductors. It is shown that if there are Cooper pairs above the superconductor critical temperature, the electric field forces the Cooper pairs to Bose condensate and the onset of the superconductivity, thereby increasing the critical temperature.
