Electronic transitions in graphene atoms induced by ultrashort pulses

This paper studies electronic transitions in artificial relativistic atoms created by charged impurities in graphene monolayers. The transitions are induced by interactions with ultrashort electromagnetic pulses. Using a non-perturbative sudden perturbation approach, analytical expressions are derived for probabilities of excitation, ionization and electron-hole pair creation processes. The dependence on pulse parameters enters only through an effective momentum transfer parameter. Calculated probabilities for the three processes are presented and analyzed.
