The electrodynamics of organic superconductors

Abstract

The electrodynamics of two classes of organic superconductors, based on the molecule BEDT-TTF, and on C60, is discussed. For both groups of materials, in the normal state the frequency dependent conductivity is that of a weakly correlated metal (with an interband transition in the inared region). We find that for representative examples of both groups of organic materials the electrodynamics of the superconducting state is in full agreement with s-wave pairing.
