Correlation effect on transport phenomena in the superconducting state Original Research Article

The method by which the transport coefficients in the superconducting state is renormalized by the electron–electron correlation is presented. We take the magnetic field penetration depth λ in the high-Tc cuprates as a typical quantity. By taking into account the effect of the Umklapp scattering consistently, the experimental data on the doping and the temperature dependence of λ is explained based on the Fermi liquid theory. The correlation term in the non-linear Meissner effect is also obtained. The corresponding experiments would test our theory.
