Dynamical effects of Pauli blocking on resonant multielectron ionization

Abstract

We examine the dynamical role of the Pauli exclusion principle on resonant multielectron ionization. Using a simple essential-state model that permits us approximate but analytical solutions, we show that this principle can lead to several unexpected consequences. It has only a transient effect on the resonant multielectron dynamics and its dynamical impact decreases with increasing Rabi frequency. Due to mutually competing mechanisms, this principle can enhance the ionization probability, while at the same time it also decreases the probability for double ionization. Furthermore, it can also manifest itself in the energy distribution of the ionized electrons, but only if the energy accumulation range of the electronic detector is chosen to be sufficiently wide.
