Example of average atomic displacement 〈Δd(t)〉 for an XTANT simulation performed for silicon with 64 atoms in the simulation box. The other parameters were: D = 3.7 eV atom−1, pulse duration of 6 fs FWHM, and photon energy of 50 eV. The atomic displacement shows thermal oscillation before irradiation. After irradiation it starts to increase quickly.
