Multielectron dynamics in the tunneling ionization of a correlated quantum system — •Maximilian Hollstein and Daniela Pfannkuche — Universität Hamburg, I. Institut für Theoretische Physik, Jungiusstraße 9, 20355 Hamburg

The multielectron dynamics during the tunneling ionization of a correlated quantum system is investigated by comparison of the solution of the time-dependent Schrödinger equation (TDSE) with the time-dependent configuration interaction singles approach (TDCIS). Here, we point out the relevance of a multielectron description of the tunnel ionization process especially for weakly confined quantum systems i.e. for instance poly-atomic molecules or semiconductor quantum dots. Within this context, we observe that adiabatic driving by an intense light field can enhance the correlations between the electrons that are still trapped.
