Momentum distributions in time-dependent density functional theory: Product phase approximation for non-sequential double ionization in strong laser fields
F. Wilken, D. Bauer
We investigate the possibility to deduce momentum space properties from time-dependent density functional calculations. Electron and ion momentum distributions after double ionizat…

Nonsequential Double Recombination in Intense Laser Fields
P. Koval, F. Wilken, D. Bauer +1
A second plateau in the harmonic spectra of laser-driven two-electron atoms is observed both in the numerical solution of a low-dimensional model helium atom and using an extended…

Adiabatic Approximation of the Correlation Function in the Density-Functional Treatment of Ionization Processes
F. Wilken, D. Bauer
The ionization of a one-dimensional model Helium atom in short laser pulses using time-dependent density functional theory is investigated. We calculate ionization probabilities as…
