High-harmonic Generation Spectroscopy in van der Waals Materials: Accessing Bloch Wavefunctions and Their Scattering Processes

High-harmonic generation (HHG) — an extreme nonlinear response to strong light fields — has emerged as a promising tool for probing femtosecond-to-attosecond electron dynamics in crystalline solids. This special topic article presents a perspective on how HHG spectroscopy has bee...
