Extraction of higher-order nonlinear electronic response to strong field excitation in solids using high harmonic generation
Seunghwoi Han, Lisa Ortmann, Hyunwoong Kim +9
State-of-the-art experiments employ strong ultrafast optical fields to study the nonlinear response of electrons in solids on an attosecond time-scale. Notably, a recent experiment…

Spectral Interference in High Harmonic Generation from Solids
Yong Woo Kim, Tian-Jiao Shao, Hyunwoong Kim +5
Various interference effects are known to exist in the process of high harmonic generation (HHG) both at the single atom and macroscopic levels. In particular, the quantum path dif…
