Ultrafast optical current in Weyl semimetals

We study theoretically the nonlinear response of Weyl semimetals to an ultrashort optical pulse . Such strong electric field induces a finite conduction band population near the Weyl points in the reciprocal space. Also, the optical pulse causes current in the system both during and after the pulse.
