This paper presents an analytic, non-perturbative approach to understanding high harmonic generation (HHG) in solids using intense, low-frequency laser pulses. The adiabatic approach allows for a closed-form solution, providing insights into the electron dynamics and HHG spectra, and offering an explanation for the dominance of interband HHG mechanisms. This is significant because it provides a theoretical framework for understanding and potentially controlling HHG in solid-state materials, which is crucial for applications like attosecond pulse generation.
