Recent Developments in Rydberg State Formation via Frustrated Tunnel Ionization

Date Mo, 20.05.2019 - Mo, 20.05.2019
Time 16:45h
Speaker Dr. Alexandra Landsman
Location ETHZ, Hönggerberg Campus, HPF G-6
Program ABSTRACT:
The process of Rydberg state formation through frustrated tunnel ionization has attracted much interest over the past decade, with recentexperiments demonstrating that it can even be used as a new source for coherent extreme-ultraviolet (XUV) emission [1]. Here we discuss some recent theoretical developments [2,3], focusing on two aspects: (i) How Rydberg states can be used as an independent test for non-adiabaticity in strong field ionization; (ii) Control of quantum number distribution of Rydberg states using laser parameters. The resulting implications for coherent XUV emission will also be addressed.
