Photogalvanic and photon drag phenomena in superconductors and hybrid superconducting systems

In this paper we review recent progress in the theoretical understanding of the peculiarities of photogalvanic phenomena, photon drag, and the inverse Faraday effects in superconductors and hybrid superconducting structures. Our study is based on the time-dependent Ginzburg-Landau theory with a complex-valued relaxation constant, which provides the simplest description of the mechanisms of the second-order nonlinear effects in the electrodynamic response and related mechanisms for the generation of dc photocurrents and magnetic moment, as well as switching between different current states under the influence of electromagnetic radiation of various polarizations.
