Abstract
With a semiclassical quasistatic model we achieve insight into the
complex dynamics of two correlated electrons under the combined influence
of a two-center Coulomb potential and an intense laser field. The
model calculation is able to reproduce experimental data of nitrogen
molecules for a wide range of laser intensities from the tunneling
to the over-the-barrier regime, and predicts a significant alignment
effect on the ratio of double over single ion yield. The classical
trajectory analysis allows us to unveil subcycle molecular double
ionization dynamics.
