Optical Science Seminar - Lisa Ortmann (The Ohio State University) - "Testing Non-adiabatic Theories of Ultrafast Strong Field Ionization"
Ultrafast strong-field ionization often happens in a regime where nonadiabaticity has to be taken into account. Yet it is still under debate how nonadiabaticity manifests itself. In this talk, two widely used nonadiabatic theories will be revisited and a scheme to test which theory describes the situation at the tunnel exit more accurately will be pre-sented. In the second part, it will be shown how electrons captured in Rydberg states by means of frustrated tunnel-ing ionization can be used as an independent nonadiaba-ticity test that does not require measurement of the abso-lute intensity, which is a problem that many other nonadi-abaticity tests struggle with.
