Supercurrent generation by spin injection in an s-wave superconductor–Rashba metal bilayer

The spin-galvanic (inverse Edelstein) and inverse spin-Hall effects are calculated for a hybrid
system that combines thin superconductor and Rashba-metal layers. These effects are produced by
a nonequilibrium spin polarization which is injected into the normal metal layer. This polarization
gives rise to an electric potential that relaxes within some characteristic length, which is determined
by the Andreev reflection. Within this length the dissipative electric current of quasiparticles in the
normal layer converts into the supercurrent. This process involves only subgap states and at the
low temperature inelastic electron-phonon interactions are not important. It is discussed how such
a hybrid system can be integrated into a SQID where it produces the effect similar to a magnetic
flux.
