Event Details & Abstract: 

The theoretical treatment of atoms and molecules exposed to ultra-short intense laser pulses is extremely challenging. Full solutions of the time-dependent Schrödinger equation are limited to systems as small as helium atoms or molecular hydrogen where in the latter case at most the vibrational but not the rotational motion is included. Therefore, simpler models are usually adopted to interpret corresponding experiments. However, the systematic investigation of their validity is very difficult due to the lack of a well defined references. Therefore, a quantum simulator based on ultra-cold atoms is presented that allows for checking the validity of strong-field models. As a consequence, processes that usually occur on an attosecond time scale can be watched in the millisecond regime, i.e. slowed down by more than ten orders of magnitude.
