Alexandra Landsman Attosecond Photoemission Delays in Atoms and Molecules

Attosecond chronoscopy has revealed small but measurable delays in photoionization, characterized by the ejection of an electron on absorption of a single photon. Ionization-delay measurements in atomic targets provide a wealth of information about the timing of the photoelectric effect, resonances, and electron correlations. However, extending this approach to molecules presents challenges, such as identifying the correct ionization channels and the effect of the anisotropic molecular landscape on the measured delays. This talk will focus on some experimental measurements of ionization delays in molecules and their theoretical interpretation.
