ABSTRACT
This chapter focuses on the interplay between optical and electronic properties, and addresses the issue of tunability of the latter using a laser field. It shows that the strong renormalizations of the electronic structure of graphene can be rationalized in a transparent way using the Floquet theory, which allows us to explore electronic and transport properties of materials in the presence of oscillating electromagnetic fields. The chapter discusses the interplay of a laser field in both the electronic structure and transport properties of graphene. The origin of the dynamical gaps will be shown to be related to an inelastic Bragg's scattering mechanism occurring in a higher-dimensional space. It describes that the width of these gaps strongly depends on the intensity, frequency, and polarization of the field. The chapter analyzes the transport properties of the model by calculating the dc conductance for laser wavelengths in the mid-infrared domain and explores the laser-induced dips for different choices of the parameters.
