Restricted-Geometry Quantum Models Beyond Atoms: Application of the Eckhardt-Sacha approach to NSDI in Diatomic Systems
Lars C. Bannow, Jan H. Thiede, Michał Ogryzek +2
We present a (1+1)-dimensional quantum model designed to describe nonsequential double ionization (NSDI) in homonuclear diatomic molecules exposed to strong linearly polarized lase…
On efficiency of double ionization of a three-electron atom in moderate laser field intensities
Dmitry Efimov
We study double ionization in a one-dimensional model of a three-electron atom exposed to strong short laser fields. The corresponding ab initio simulations reveal a characteristic…
Quantum versus semi-classical signatures of correlated triple ionization in Dalitz plots
Dmitry K. Efimov, Georgios P. Katsoulis, Tymoteusz Rozpętkowski +3
We investigate correlated three-electron escape in Ne when driven by an intense, infrared laser field. We do so by employing a reduced-dimensionality quantum-mechanical model and t…
Hyperfine interaction in the Autler-Townes effect II: control of two-photon selection rules in the Morris-Shore basis
Arturs Cinins, Dmitry K. Efimov, Martins Bruvelis +6
We investigated the absence of certain bright peaks in Autler-Townes laser excitation spectra of alkali metal atoms. Our research revealed that these dips in the spectra are caused…
Strong-Field Double Ionization in a Three-Electron Atom: Momentum Distribution Analysis
Dmitry K. Efimov, Artur Maksymov, Jakub Zakrzewski +1
We study strong-field double ionization in a three-electron atom by applying a simplified, reduced-dimensionality model with three active electrons. The influence of the spin-induc…
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…
A systematic construction of Gaussian basis sets for the description of laser field ionization and high-harmonic generation
Aleksander P. Woźniak, Michał Lesiuk, Michał Przybytek +8
A precise understanding of mechanisms governing the dynamics of electrons in atoms and molecules subjected to intense laser fields has a key importance for the description of attos…
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…
