Research on isolated attosecond pulses (IAPs) based on high-order harmonic generation
changed substantially around 2010. Before then, the Ti: sapphire laser was the de facto …

Key properties of quantum materials stem from dynamic interaction chains that connect
stable electronic quasiparticles through short-lived coherences, which are difficult to control …

Extreme ultraviolet (EUV) radiation is a key technology for material science, attosecond
metrology, and lithography. Here, we experimentally demonstrate metasurfaces as a …

Recent progress in high power ultrafast short-wave and mid-wave infrared lasers has
enabled gas-phase high harmonic generation (HHG) in the water window and beyond, as …

Electron migration in molecules is the progenitor of chemical reactions and biological
functions after light-matter interaction. Following this ultrafast dynamics, however, has been …

Advances in attosecond science have led to a wealth of important discoveries in atomic,
molecular, and solid-state physics and are progressively directing their footsteps toward …

High-harmonic generation (HHG) in solids has emerged in recent years as a rapidly
expanding and interdisciplinary field, attracting attention from both the condensed-matter …

Since the first demonstration of the generation of attosecond pulses (1 as= 10− 18 s) in the
extreme-ultraviolet spectral region, several measurement techniques have been introduced …

We investigate theoretically high-harmonic generation (HHG) in bulk crystals exposed to
intense midinfrared lasers with photon energies smaller than the band gap. The two main …

High-harmonic generation (HHG) is an extreme nonlinear process in which intense pulses
of light drive matter to emit high harmonics of the driving frequency, reaching the extreme …
