Higher-Order Corrections Due to the Order Parameter to the Flux Flow Conductivity of Dirty Type II Superconductors
An early theory of the flux flow resistivity of dirty type II superconductors proposed by Caroli and Maki2 appeared to explain the observed phenomenon rather well. However, Thompson3 and Takayama and Ebisawa4 later pointed out that in the calculation of Caroli and Maki (CM) some diagrams which describe the additional dissipation of electronic current due to the presence of the order parameter Δ(r) had been neglected. The inclusion of this new term, which we call the anomalous term, certainly destroys the good agreement so far found between the theory and experiments. In order to resolve this discrepancy, we will study systematically the higher-order corrections in the order parameter to the flux flow conductivity.
