Adiabatic HHG in Solids: Analytic Description
Analysis
Key Takeaways
- •Presents an analytic, non-perturbative approach to HHG in solids.
- •Utilizes an adiabatic approach for closed-form solutions.
- •Provides insights into electron dynamics and HHG spectra.
- •Explains the dominance of interband HHG mechanisms.
- •Offers a theoretical framework for understanding and controlling HHG.
“Closed-form formulas for electron current and HHG spectra are presented. Based on the developed theory, we provide an analytic explanation for key features of HHG yield and show that the interband mechanism of HHG prevails over the intraband one.”
