Abstract

We have analyzed what new fundamental information on the properties of superconductors can be obtained by systematic investigation of the Bernoulli effect. We show that the latter is a tool to determine the effective mass of Cooper pairs, the volume density of charge carriers, the temperature dependence of the penetration depth and the condensation energy. To this end, the theoretical results for disordered and anisotropic-gap superconductors are systematized. For clean anisotropic-gap superconductors we present a simple derivation of the temperature dependence of the penetration depth.
