Floquet states and optical conductivity of an irradiated two dimensional topological insulator
S. Sajad Dabiri, H. Cheraghchi, A. Sadeghi
We study the topology of the Floquet states and time-averaged optical conductivity of the lattice model of a thin topological insulator subject to a circularly polarized light usin…

Theory of nonlinear optical response
Amin Maleki Sheikhabadi, Zahra Bagheri, Ali Sadeghi
We present a general formalism for investigating the second-order optical response of solids to an electric field in weakly disordered crystals with arbitrarily complicated band st…
