The HeH⁺ ion in intense asymmetric field — •Saurabh Mhatre and Stefanie Gräfe — Institut für Physikalische Chemie, Friedrich-Schiller-Universität Jena, Helmholtzweg 4, 07743 Jena, Deutschland

We investigate the dynamics of dissociation and ionization of highly asymmetric HeH⁺ ion. The large mass and electronic asymmetry in the HeH⁺ ion makes it an ideal candidate for the dynamics in few-cycle intense laser pulses. We employ our recently developed semi-classical dressed surface hopping model to simulate all possible fragmentation pathways such as dissociation, single and double ionization. These pathways can be accessed in multiphoton as well as tunnelling regime. By using specifically tailored femtosecond pulses, we aim to control these fragmentation pathways.
