Prevalence of different double ionization pathways in driven atomic and molecular systems

We present in a three-dimensional quasiclassical framework a unified way of exloring double ionization in strongly driven atomic and molecular systems. We identify and explore different double ionization pathways and compare the results for atomic and molecular systems. We also show that correlated electron momenta probe the tunnelling phase of the re-colliding electron in N2. Finally we present results for the double ionization pathways in the full fragmentation of H2 which are in good agreement with experimental results.
