The Influence of Metal Nanoparticles on the Propagation of Extremely Short Optical Pulses in Graphene

Resumo

The propagation of two-dimensional extremely short optical pulses in graphene with metal nanoparticles has been investigated. The effects that are observed when changing the parameters of the effective Hamiltonian, which takes into account the exchange interaction, have been studied. It has been revealed that the introduction of metallic adatoms into graphene leads to an increase in the amplitude of the pulse. This effect can be enhanced by choosing a particular metal particle .
