NCCR MUST at Scientifica 2021Photo-ionization by strong IR fields

| Program | With quasi-static tunneling and the strong field approximation we have beautifully simple physical models that qualitatively explain photo-ionization of atoms and molecules by strong, long wave-length fields. However, high-precision measurements have long advanced beyond the limitations of these models. The most prominent of these limitations are imposed by polarization of the system before ionization, scattering of the electron after ionization, and multi-electron effects. The distinction of "before" and "after" ionization requires the definition of an "ionization time", which is a quite elusive concept. Numerical simulation can illustrate conceptual difficulties, expose model limitations, and in simple cases provide reliable theoretical data. After discussing conceptual questions of strong field ionization, available numerical techniques and their possibilities will be briefly introduced. Finally, evidence for polarization and multi-electron effects will be presented. |
