Three-electron correlations in strong laser field ionization: Spin induced effects
Dmitry Efimov, Artur Maksymov, Marcelo Ciapina +3
Strong field processes in the non-relativistic regime are insensitive to the electron spin, i.e. the observables appear to be independent of this electron property. This does not h…
Strong-field triple ionization of atoms with valence shell
Jakub S. Prauzner-Bechcicki, Dmitry K. Efimov, Michał Mandrysz +1
The interaction of strong pulsed femtosecond laser field with atoms having three equivalent electrons in the outer shell ( configuration, e.g. nitrogen) is studied via numeric…
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…
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…
