Impact of coherent phonon dynamics on high-order harmonic generation in solids — •Jinbin Li^1,2, Ulf Saalmann², Hongchuan Du¹, and Jan Michael Rost² — ¹School of Nuclear Science and Technology, Lanzhou University, Lanzhou, China — ²Max Planck Institute for the Physics of Complex Systems, Dresden, Germany

We theoretically investigate the impact of coherent phonon dynamics on high-order harmonic generation (HHG), as recently measured [Hollinger et al., EPJ Web of Conferences 205, 02025 (2019)]. A method to calculate HHG in solids including phonon excitation is developed for a model solid. Within this model we calculate the signal of specific harmonics as a function of a pump-probe delay in the pico-second range. The characteristic behavior of the harmonic signal is traced back to underlying phonon dynamics.
