Dirac fermion time-Floquet crystal: manipulating Dirac points

We demonstrate how to control the spectra and current flow of Dirac electrons in both a graphene sheet and a topological insulator (TI) by applying either two linearly polarized laser fields with frequencies ω and 2ω or a monochromatic (one-frequency) laser field together with a spatially periodic s...
