Ionization of small Argon clusters in intense laser pulses at different wavelengths — •Mehrdad Baghery, Ulf Saalmann, and Jan-Michael Rost — Max Planck Institute for the Physics of Complex Systems, Dresden, Germany

Electrons in clusters, after absorbing energy from a laser field, may not be bound to a specific atom any more, but may still be bound to the cluster as a whole. These electrons may then absorb further energy through inverse Bremsstrahlung and cause other electrons to ionize through collisions. These phenomena make the dynamics of clusters non-trivial.

Since hybrid quantum-classical calculations are usually computationally less expensive than those of a full quantum description, a hybrid quantum-classical model which reproduces quantum predictions may be beneficial to future research. We are presenting such a model for small Argon clusters interacting with intense laser pulses.
