Ultrafast strong-field absorption in gapped graphene
S. Azar Oliaei Motlagh, Ahmal Jawad Zafar, Aranyo Mitra +2
We study theoretically the strong-field absorption of an ultrafast optical pulse by a gapped graphene monolayer. At low field amplitudes, the absorbance in the pristine graphene is…

Ultrafast optical currents in gapped graphene
S. Azar Oliaei Motlagh, Fatemeh Nematollahi, Aranyo Mitra +3
We study theoretically the interaction of ultrashort optical pulses with gapped graphene. Such strong pulse results in finite conduction band population and corresponding electric…
