标题： Spin-resolved orbital magnetization in Rashba two-dimensional electron gas

摘要： 我们在具有Rashba类型自旋-轨道相互作用的二维电子气中计算了轨道自旋依赖的磁化强度。 这种轨道磁化是由系统的时间反演对称性所允许的，并且当系统不在热平衡状态时会产生自旋电流。 理论方法基于线性响应理论和Matsubara格林函数形式。 为了考虑自旋分辨的轨道磁化强度，引入了一个自旋依赖的矢量势。 由于自旋分辨的轨道磁化强度而在热不平衡状态下出现的自旋电流在自旋能斯特效应中起着重要作用，并且必须包括在内以正确描述低温下的自旋能斯特电导率。 显示英文摘要

摘要： We calculate orbital spin-dependent magnetization in a two-dimensional electron gas with spin-orbit interaction of Rashba type. Such an orbital magnetization is admitted by the time-reversal symmetry of the system, and gives rise to spin currents when the system is not in thermal equilibrium. The theoretical approach is based on the linear response theory and the Matsubara Green's function formalism. To account for the spin-resolved orbital magnetization a spin-dependent vector potential has been introduced. The spin currents which appear in thermal nonequilibrium due to the spin-resolved orbital magnetization play an important role in the spin Nernst effect, and have to be included in order to correctly describe the low-temperature spin Nernst conductivity.
