Three-level Spaser System: a Semi-Classical Analysis
Rupesh Ghimire, Dalton . C. Hunley, Fatemeh Nematollahi +3
We theoretically study a nanospaser system, which consists of a spherical silver nanoparticle embedded inside a sphere composed of dye molecules. The gain of the system, dye molecu…
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…
Topological resonance in Weyl semimetals in circularly-polarized optical pulse
Fatemeh Nematollahi, S. Azar Oliaei Motlagh, Jhih-Sheng Wu +3
We study theoretically the ultrafast electron dynamics of three-dimensional Weyl semimetals in the field of a laser pulse. For a circularly-polarized pulse, such dynamics is govern…
