Strong-field ionization of atoms with valence shell: Two versus three active electrons
Dmitry K. Efimov, Jakub S. Prauzner-Bechcicki, Jakub Zakrzewski
For a model atom with the valence shell we construct consistent three- and two-active electrons models enabling their direct comparison. Within these models, we study the inf…
Double ionization of a three-electron atom: Spin correlation effects
Dmitry K. Efimov, Jakub S. Prauzner-Bechcicki, Jan H. Thiede +2
We study the effects of spin degrees of freedom and wave function symmetries on double ionization in three-electron systems. Each electron is assigned one spatial degree of freedom…
Symphony on Strong Field Approximation
Kasra Amini, Jens Biegert, Francesca Calegari +22
This paper has been prepared by the Symphony collaboration (University of Warsaw, Uniwersytet Jagielloński, DESY/CNR and ICFO) on the occasion of the 25th anniversary of the "simpl…
Ab initio study of time-dependent dynamics in strong-field triple ionization
Jan H. Thiede, Bruno Eckhardt, Dmitry K. Efimov +2
An ab initio analysis of strong-field three-electron ionization in a restricted-dimensionality model reveals the dynamics of the ionization process and the dominant channels for do…
Restricted space ab initio models for double ionization by strong laser pulses
Dmitry K. Efimov, Artur Maksymov, Jakub S. Prauzner-Bechcicki +5
Double electron ionisation process occurs when an intense laser pulse interacts with atoms or molecules. Exact {\it ab initio} numerical simulation of such a situation is extremely…
