Abstract
The propagation of an extremely short optical pulse in a thin-film topological insulator has been considered. The electrons are described by a low-temperature long-wavelength effective Hamiltonian, whereas the electromagnetic field is treated classically within the Maxwell’s equations. The dependence on the velocity and maximum amplitude of the extremely short pulse has been revealed.
