TMDC-based topological nanospaser: single and double threshold behavior
Rupesh Ghimire, Fatemeh Nematollahi, Jhih-Sheng Wu +2
We theoretically study a topological nanospaser, which consists of a silver nanospheroid and MoS monolayer ake of a circular shape. The metal nanospheroid acts as a plasmonic n…
Femtosecond currents in transition metal dichalcogenides monolayers
S. Azar Oliaei Motlagh, Vadym Apalkov, Mark I. Stockman
We theoretically study the interaction of an ultrafast intense linearly polarized optical pulse with monolayers of transition metal dichalcogenides (TMDCs). Such a strong pulse red…
Anomalous Ultrafast All-Optical Hall Effect in Gapped Graphene
S. Azar Oliaei Motlagh, Vadym Apalkov, Mark I. Stockman
We propose an ultrafast all-optical anomalous Hall effect in two-dimensional (2D) semiconductors of hexagonal symmetry such as gapped graphene (GG), transition metal dichalcogenide…
Ultrafast valley polarization in bilayer graphene
Pardeep Kumar, Thakshila M. Herath, Vadym Apalkov
We study theoretically interaction of a bilayer graphene with a circularly polarized ultrafast optical pulse of a single oscillation at an oblique incidence. The normal component o…
Bilayer graphene in strong ultrafast laser fields
Pardeep Kumar, Thakshila M. Herath, Vadym Apalkov +1
We theoretically investigate the interaction of an ultrastrong femtosecond-long linearly polarized optical pulse with AB-stacked bilayer graphene. The pulse excite electrons from t…
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…
