Spin current and its superfluid
报告介绍 报告摘要: In this talk, I will review some basic physical properties of spin current. Furthermore, I will present our recent theoretical study of the possible existence of a spin superfluid (SSF) in a ferromagnetic graphene system. The spin superfluid, a counterpart to the charge superconductor, in which a spin-polarized electron-hole excitons play the roles of the ‘Cooper’ pairs. We present a BC...
