The electronic degrees of freedom are treated quantum mechanically within the time-dependent Kohn–Sham formalism, while the ions are handled classically. All quantities are expanded in a regular mesh in real space, and the simulations are performed in real time. Although not optimized for that purp...

The electronic degrees of freedom are described within the Kohn-Sham form of the time-dependent density functional theory, while nuclei are treated as classical point particles.
