Nondipole electron momentum offset as a probe of correlated three-electron ionization in strongly driven atoms

GP Katsoulis, MB Peters, A Emmanouilidou - Physical Review A, 2023 - APS
We employ a recently developed three-dimensional semiclassical model to identify
nondipole effects in triple ionization of Ne driven by infrared laser pulses at intensities where …

Quantum versus semi-classical signatures of correlated triple ionization in Dalitz plots

DK Efimov, GP Katsoulis, T Rozpętkowski… - arXiv preprint arXiv …, 2024 - arxiv.org
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 …
