Effects of Coulomb Interaction on Superconductivity

  • Yasutami Takada

Abstract

In recent high-Tc oxide[l] and heavy-fermion[2] superconductors, electron (or hole) correlations are important in understanding their mechanisms of superconductivity. At present, however, we have only a little knowledge about the effects of the Coulomb interaction on superconductivity.[3] In the conventional theory, all the Coulomb effects are pushed into a single parameter μ*, called the Coulomb pseudo-potentialf4] which is regarded as a phenomenological parameter.
