Resumo

We developed a theoretical model of the interaction of a photonic crystal made of semiconductor carbon nanotubes and a three-dimensional extremely short laser pulse in the presence of an external magnetic field. Based on numerical simulations, pictures of the time evolution of current density in a medium containing multi-level impurity are shown. The dependences of the shape of the current density on the values of the external magnetic field and on the hopping integrals between impurity levels have been established.
