Reply to “Comment on ‘Origin of symmetry-forbidden high-order harmonic generation in the time-dependent Kohn-Sham formulation’”

In reply to the Comment by O. Neufeld et al. [Phys. Rev. A 105, 047101 (2022)], we argue that conclusions of Phys. 103, 043106 (2021) remain valid. We disprove claim unphysical even-order harmonics originate from convergence issues related reflections at boundary simulation box. By additional calculations, show such perturb high-order harmonic generation spectra oscillations with periods much smaller than distance between harmonics. also demonstrate argument Comment, in contrast our multielectron excitations argument, cannot explain why there are no one-electron systems. Moreover, put forward conclude time-dependent Kohn-Sham equations superior natural is not
