Photogalvanic and photon drag phenomena in superconductors and hybrid superconducting systems

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

Superconducting photocurrents induced by structured electromagnetic radiation

We develop a phenomenological theory describing the interaction of superconducting condensate with a Bessel beam of twisted light characterized by a nonzero angular momentum $m$. Starting from the time-dependent Ginzburg-Landau model with the complex relaxation time we calculate the spatial profiles of dc photoinduced currents and magnetic fields as well as the second harmonic response. The photocurrents and magnetic fileds are shown to be determined both by the helicity of light and its orbital momentum $m$. Analyzing the half-space and thin film geometries we discuss possible experimental tests aimed to probe the superconducting photocurrents and magnetic fields.
