Disorder effects on the origin of high-order harmonic generation in solids
Koki Chinzei, Tatsuhiko N. Ikeda
Abstract
The authors identify the coherent and the incoherent contributions of the High-order Harmonic Generation (HHG) in disordered solids. HHG is dominated by coherent potential scatterings for the weak disorder while by incoherent ones for the strong disorder. This finding also highlights the different underlying mechanisms of the HHG in solids and gases.
