Abstract

A theory of the interaction between a cnoidal electromagnetic wave and the electron subsystem of a Dirac crystal is constructed within the Floquet formalism. The Floquet spectrum of an electron in the high-frequency electric field of a cnoidal profile is calculated. The possibilities of dynamically induced band valleys and the formation of an energy gap at the Dirac point are investigated.
