Hydrodynamic theory of chiral angular momentum generation in metals

We present a hydrodynamic theory to describe chiral electron system with Weyl spin-orbit interaction on field-theoretic basis. Evaluating the momentum flux density as linear response driving electric field, we derive an equation of motion for orbital angular momentum. It is shown that nature leads dynamic bulk generation by inducing global torque applied field.
