Nonlinear optical properties of bilayer graphene with rahsba spin-orbit interaction in terahertz regime

摘要

We explore the third order nonlinear optical conductivity of the bilayer graphene in the terahertz regime where the Rashba spin-orbit coupling interaction is taken into account. It is found that nonlinear optical conductivity of the BLG with ROI is significantly enhanced in comparison with the case without the ROI.
