Abstract:

The nonlinear field dependence of the so-called anomalous term in the electric conductivity due to the fluctuation of the superconducting order parameter is studied theoretically. It is found that in the limit of a large electric field E (i.e. E≫E_c=√3/Dε₀(T)^3/2/e where ε₀(T)=8/π(T-T_c) and D is the diffusion constant), the anomalous term becomes twice as large as the Aslamazov-Larkin term independent of the dimensionality of the system and independent of the pair-breaking parameter δ.
