@article{MrudulM2019DirectNO, title={Direct numerical observation of real-space recollision in high-order harmonic generation from solids}, author={S. MrudulM. and Adhip Pattanayak and Misha Ivanov and Gopal Dixit}, journal={Physical Review A}, year={2019} }

Real-space picture of electron recollision with the parent ion guides our understanding of the highly nonlinear response of atoms and molecules to intense low-frequency laser fields. It is also among several leading contestants for the dominant mechanism of high harmonic generation (HHG) in solids, where it is typically viewed in the momentum space, as the recombination of the conduction band electron with the valence band hole, competing with another HHG mechanism, the strong-field driven…
