Abstract
Strong field ionization of atoms and molecules is often viewed as electron tunneling through the barrier created by the laser field and core potential. In multielectron systems new tunneling channels driven by electron correlations may arise leading to complex attosecond dynamics of electron rearrangement [1]. High harmonic spectroscopy [2] provides an opportunity to record these complex dynamics in the light emitted when the liberated electron re-encounters the parent ion and recombines with the hole in the process known as high harmonic generation. One of the way of recording these complex rearrangement dynamics is time-resolving the tunneling process.
