Abstract

We analyze equilibrium spin currents in a two-dimensional electron gas with a Rashba spin-orbit interaction (Rashba medium). In a uniform Rashba medium, these currents are constant, and their ability to really transport spin is not evident. However, even the weak inhomogeneity of the Rashba medium allows one to reveal that equilibrium spin currents can transport spin from areas where spin is produced to areas where spin is absorbed.
