Spectral properties of high-order harmonic radiation enhanced by XUV-driven electron-hole dynamics
R. Esteban Goetz, Anh-Thu Le
We analyze the spectral properties of high-order harmonic radiation with photon energies extending beyond the regular cutoff energy in standard high-order harmonic generation. The…

Highly accurate semiclassical strong-field Herman-Kluk propagator method for high-harmonic generation
Phi-Hung Tran, Hao Quan Truong, R. Esteban Goetz +1
We extend our recently developed semiclassical strong-field Herman-Kluk propagator (SFHK) method to calculate high-order harmonic generation (HHG) for atoms in intense lasers. We s…
