Coulomb scattering in strong laser fields — •Sebastian Bauch and Michael Bonitz — Christian-Albrechts-Universität Kiel, Institut für theoretische Physik und Astrophysik, Leibnizstraße 15, 24098 Kiel, Germany
Progress in experiments 1leads to increasing interest in understanding interaction of atoms with an electromagnetic field in the high intensity regime. Well known effects are the generation of higher harmonics and the above threshold ionization which leads to a generation of high energetic electrons. We solve the multidimensional timedependent Schrödinger equation in the Kramers-Henneberger frame in dipole approximation and present numerical calculations of ionization processes for bound state electrons and electron wave packet scattering processes in strong laser fields for model systems. Recent calculations for electron scattering on a single 1D screened Coulomb potential 2are extended to multidimensional systems as well as to potential chains. The fast electron spectrum is analyzed.
