Monte Carlo Wave Packet Theory of Dissociative Double Ionization

Nuclear dynamics in strong-field double ionization processes is predicted using a stochastic Monte Carlo wave packet technique. Using input from electronic structure calculations and strong-field electron dynamics the description allows for field-dressed dynamics within a given molecule as well as transitions between several different charge states. The description is computationally efficient and applicable to a wide range of systems. As a proof of principle, theoretical nuclear kinetic energy release spectra for H(2) (D(2)) in strong near-infrared laser pulses of 40 fs duration are compared to experiments and very good agreement is obtained.
