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…
Fundamentally fastest optical processes at the surface of a topological insulator
S. Azar Oliaei Motlagh, Jhih-Sheng Wu, Vadym Apalkov +1
We predict that a single oscillation of a strong optical pulse can significantly populate the surface conduction band of a three-dimensional topological insulator, Bi2Se3. Both lin…
