Abstract
We use classical simulations to analyze the dynamics of nonsequential
double-electron short-pulse photoionization. We utilize a microcanonical
ensemble of 10(5) two-electron "trajectories," a number large enough
to provide large subensembles and even sub-subensembles associated
with double ionization. We focus on key events in the final doubly
ionized subensemble and back-analyze the subensemble's history, revealing
a classical slow-down scenario for nonsequential double ionization.
We analyze the dynamics of these slow-down collisions and find that
a good phase match between the motions of the electrons can lead
to very effective energy transfer, followed by escape over a suppressed
barrier.
