Numerical investigations of tunneling times — •Nicolas Teeny, Heiko Bauke, and Christoph H. Keitel — Max-Planck-Institut für Kernphysik Saupfercheckweg 1, 69117 Heidelberg

Tunnel ionization belongs to the fundamental processes of atomic physics and has been investigated in-depth experimentally as well as theoretically. The question, however, how long it takes for an electron to escape from an attractive potential could not yet be answered conclusively. In our contribution, we utilize numerical solutions of the time-dependent Schrödinger and Dirac equations to identify tunneling times [1]. The numerical results are compared with predictions based on theoretical calculations [2].
