Proper definition of spin current in spin-orbit coupled systems.

Junren Shi¹, Ping Zhang, Di Xiao, Qian Niu.

Abstract

The conventional definition of spin current is incomplete and unphysical in describing spin transport in systems with spin-orbit coupling. A proper and measurable spin current is established in this study, which fits well into the standard framework of near-equilibrium transport theory and has the desirable property to vanish in insulators with localized orbitals. Experimental implications of our theory are discussed.
