Contrasting ultrafast light-driven electron-hole interaction dynamics in monolayer MoS and metallic NbSe
Aday Cárdenas, Rui E. F. Silva, Álvaro 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…

Giant enhancement of attosecond tunnel ionization competes with disorder-driven decoherence in silicon
D. N. Purschke, D. Vick, A. Cárdenas +16
High-harmonic generation (HHG) is a strong-field phenomenon that is sensitive to the attosecond dynamics of tunnel ionization and coherent transport of electron-hole pairs in solid…
