在场论的基础上,提出了一种描述具有Weyl自旋轨道相互作用的手性电子系统的流体力学理论。将动量通量密度视为驱动电场的线性响应,推导出轨道角动量的运动方程。结果表明,手性特性通过诱导全局转矩作为对外加场的响应而产生动态体角动量。考虑旋转粘度,计算了稳态角动量。
We present a hydrodynamic theory to describe a chiral electron system with a Weyl spin-orbit interaction on a field-theoretic basis. Evaluating the momentum flux density as a linear response to a driving electric field, we derive an equation of motion for the orbital angular momentum. It is shown that the chiral nature leads to a dynamic bulk angular momentum generation by inducing a global torque as a response to the applied field. The steady-state angular momentum is calculated taking into account rotational viscosity.
