“…Theoretical studies currently employ methods of varying quantitative power to model the interaction of solid state targets with the pulsed electric fields considered in HHG. These methods include solution of the time-dependent Schrodinger equation [19][20][21], onedimensional models [22][23][24][25][26], density matrix models [27][28][29] and ab initio descriptions like time-dependent density functional theory (TDDFT) [30][31][32][33][34]. Recently, theories have also been developed to describe HHG in more complex targets such as bulk surfaces [35][36][37] and metasurfaces [38].…”

We study high order harmonics generation (HHG) in crystalline silicon and diamond subjected to near and mid-infrared laser pulses. We employ time-dependent density functional theory and solve the time-dependent Kohn-Sham equation in the single-cell geometry. We demonstrate that clear and clean HHG spectra can be generated with careful selection of the pulse duration. In addition, we implement dephasing effects through a displacement of atomic positions in a silicon large super-cell prepared by a molecular dynamics simulation. We compare our results with the previous calculations by Floss et al.
