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…

Femtosecond pulse parameter estimation from photoelectron momenta using machine learning

Tomasz Szołdra, Marcelo F. Ciappina, Nicholas Werby +4

Deep learning models have provided huge interpretation power for image-like data. Specifically, convolutional neural networks (CNNs) have demonstrated incredible acuity for tasks s…

Pulse length effects in long wavelength driven non-sequential double ionization

H. Jiang, M. Mandrysz, A. Sanchez +8

We present a joint experimental and theoretical study of non-sequential double ionization (NSDI) in argon driven by a 3100-nm laser source. The correlated photoelectron momentum di…

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…

Rescattering effects in streaking experiments of strong-field ionization

Michał Mandrysz, Matthias Kübel, Jakub Zakrzewski +1

Strong field ionization provides a unique mean to address complex dynamics of an electron in competing Coulomb and laser fields. Recent streak camera experiment (Kübel, et al., Phy…
