Abstract given by the source: Measuring and thus understanding the exact mechanisms behind charge migration in atoms and molecules is an ongoing quest with a broad range of applications. A major challenge lies in the ultrashort time scale on which these processes occur, between femtoseconds and attoseconds. I plan to further develop a recently demonstrated technique called quantum-trajectory selection (QTS). Here recollision dynamics in atoms or molecules are initiated in a precisely controlled way by overlapping attosecond pulses in the eXtreme UltraViolet (XUV) with an infrared laser field. The XUV pulse sets a clock for the start of the process and also limits the different quantum trajectories that are possible to a narrow range. The project is devided into two parts: First, an existing setup will be upgraded to allow for high energy and high XUV photon flux by building on insights from my previous research of multi-color laser drivers. Additional clocking capabilities will be investigated by using a multi-color infrared laser field on the target while investigating Auger decays in Krypton and small molecules.The project will be carried out at The Ohio State University under the supevision of Louis DiMauro and the University of Gothenburg in the group of Raimund Feifel, over a total length of three years.
