High-order Harmonic Generation from Crystalline Solids

COMPREHENSIVE EXAM

Speaker: Dian Peng

Abstract:
While theoretical understanding of high-order harmonic generation (HHG) from gases is well-developed, theoretical understanding of HHG from periodic (solid) materials is less developed. Ghimire et al. (2011) observed firstly the non-perturbative transmission high-order harmonics (up to 25th harmonic) from a bulk crystal. Since then, there has been renewed interests in experiments of HHG from solids, and theoretical debates on the physical mechanisms. In this report, I will review selected current theoretical approaches of HHG from crystalline solids, discuss the agreement level of theoretical description with experiments, and provide ideas for possible improvements.
