Attosecond time delays in molecules, clusters and liquids: towards electronic dynamics in solutions

Date Di, 12.10.2021 - Di, 12.10.2021
Time 16:00
Speaker Prof. Hans Jakob Wörner
Location Online
Program Attosecond spectroscopy has enabled the observation of ionization dynamics on their natural time scale. These delays convey rich information on the scattering potential of the ionized system, as well as electronic correlations. In this lecture, I will discuss the experimental measurement of time delays in molecules [1]. Turning from gases to liquids, I will discuss the measurement of photoionization delays from liquid water [2] and the development of theoretical methods for their interpretation. Extending attosecond spectroscopy to size-resolved water clusters provided a bridge between the gas and liquid phases and yielded a molecular-level understanding of the mechanisms governing photoionization dynamics in the condensed phase [3]. A systematic correlation between the ionization delay and the spatial extension of the electron hole has been found, which suggests the possibility of studying electron-hole dynamics in weakly bound clusters and liquids with attosecond temporal resolution. These methods establish an experimental pathway to time-resolved studies of electronic dynamics in (micro-)solvated molecules.
