High-Order Harmonic Generation Spectroscopy of Correlation-Driven Electron Hole Dynamics

Abstract

We show how high-order harmonic generation spectroscopy can be used to follow correlation-driven electron hole dynamics with attosecond time resolution. The technique is applicable both to normal Auger transitions and to electron hole migration processes that do not lead to secondary electron emission. We theoretically simulate the proposed spectroscopy for M(4,5)NN Auger decay in Kr and for correlation-driven inner-valence hole dynamics in trans-butadiene and propanal.
