High-order nonlinear optical response of a twisted bilayer graphene
Tatsuhiko N. Ikeda
Abstract
This paper reports nonperturbative numerical calculations for nonlinear optical responses of a twisted bilayer graphene. The twist has shown to activate various orders of harmonics that cannot occur in monolayer or conventional bilayer graphene.
