Effective electron-electron interaction in metals and superconductors

Abstract

The effective electron-electron interaction (EEEI) arising in metals and superconductors due to exchange of virtual quasiparticles is investigated. The quasiparticles such as phonons, scalar and vector photons, and magnons in ferromagnetic metals are taken into consideration. The energy relaxation time and the conductivity induced by EEEI are calculated.
