Chirality in Weyl semimetals in strong circularly-polarized electric field

ORAL

Abstract

We theoretically study the interaction of three-dimensional topological Weyl semimetals with a single oscillation femtosecond long circularly-polarized pulse. The chiral pulse causes a finite electron population of the conduction band which is highly structured and is determined by the topological resonance. These textures can be probed by a linear pulse applied after the circularly-polarized pulse. The response of the system to the linear probe pulse is highly sensitive to the chirality of the circular pulse. Also, the pulse which consists of two oscillations of different chiralities causes conduction band population distribution in the reciprocal space which is highly chiral and is related to the intrinsic chirality of Weyl semimetals.
