Programmable high-harmonic emission in solids through photon pathways
Pieter J. van Essen, Aday Cárdenas, Rui E. F. Silva +2
Ultrafast all-optical control of light emission is a central goal of extreme nonlinear optics, with implications for compact short-wavelength sources, petahertz optoelectronics, an…
Contrasting ultrafast light-driven electron-hole interaction dynamics in monolayer MoS and metallic NbSe
Aday Cárdenas, Rui E. F. Silva, Ãlvaro Jiménez-Galán
We study strong-field driven ultrafast dynamics and high-harmonic generation (HHG) in monolayer 2H-NbSe and compare them with those of monolayer 2H-MoS by solving the multi…
Effects of Zero-Point Motion in the High Harmonic Generation Spectrum of Solids
Aday Cárdenas, David N. Purschke, Graham G. Brown +3
The interpretation of high-harmonic generation (HHG) in solids typically relies on phenomenological dephasing times far shorter than what is expected from microscopic scattering pr…
Unambiguous discrimination of high harmonic generation mechanisms in solids
Graham G. Brown, Rui E. F. Silva, Ãlvaro Jiménez-Galán +2
Using real-space view of high harmonic generation (HHG) in solids, we develop a physically transparent and gauge-invariant approach for distinguishing intraband and interband HHG m…
High Harmonic Generation from a Noble Metal
Shima Gholam-Mirzaei, Aleksey Korobenko, Nida Haram +11
High-harmonic generation (HHG) in solids has typically been explored in transparent dielectrics and semiconductors. Metals have long been dismissed due to their strong reflectivity…
