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…
Near-field edge fringes at sharp material boundaries
Viktoriia E. Babicheva, Sampath Gamage, Mark I. Stockman +1
We have studied the formation of near-field fringes when sharp edges of materials are imaged using scattering-type scanning near-field optical microscope (s-SNOM). Materials we hav…
Attosecond nanoscale near-field sampling
Benjamin Förg, Johannes Schoetz, Frederik Suessmann +15
The promise of ultrafast light field driven electronic nanocircuits has stimulated the development of the new research field of attosecond nanophysics. An essential prerequisite fo…
Strong-Field Perspective on High-Harmonic Radiation from Bulk Solids
Takuya Higuchi, Mark I. Stockman, Peter Hommelhoff
Mechanisms of high-harmonic generation from crystals are described by treating the electric field of a laser as a quasi-static strong field. Under the quasi-static electric field,…
Nanoconcentration of Terahertz Radiation in Plasmonic Waveguides
Anastasia Rusina, Maxim Durach, Keith A. Nelson +1
Recent years have seen an explosive research and development of nanoplasmonics in the visible and near-infrared (near-ir) frequency regions. One of the most fundamental effects in…
