Effect of Interactions on the Quantization of the Chiral Photocurrent for Double-Weyl Semimetals
The circular photogalvanic effect (CPGE) is the photocurrent generated in an optically active material in response to an applied AC electric field, and it changes sign depending on the chirality of the incident circularly polarized light. It is a non-linear DC current as it is second order in the ap...
