Abstract

Motivated by recent experiments [ I. J. Vera-Marun, V. Ranjan and B. J. van Wees Nat. Phys. 8 313 (2012)], we formulate a nonlinear theory of spin transport in quantum coherent conductors. We show how a mesoscopic constriction with energy-dependent transmission can convert a spin current injected by a spin accumulation into an electric signal, relying neither on magnetic nor exchange fields. When ...
