Extracting inter-nuclear distances in the oxygen molecule interacting with an XFEL-pulse: a fundamental system for understanding Coulomb explosion imaging
Zixu Wang, Georgios Petros Katsoulis, Giorgio Visentin +3
We investigate the interaction of O with an X-ray Free Electron laser (XFEL) pulse of short duration. We consider a photon energy of 570 eV, which allows for the formation of…
Enhanced nondipole momentum offsets in triple ionization of atoms driven by mid-infrared laser fields
Samuel James Praill, Georgios Petros Katsoulis, Daria Romero Torres +1
We investigate the dependence on wavelength of nondipole effects in triple ionization of Ne driven by intense infrared and mid-infrared laser pulses using a three-dimensional semic…
Multielectron ionization in O driven by intense infrared laser pulses
Georgios Petros Katsoulis, Agapi Emmanouilidou
We extend a recently developed three-dimensional semiclassical model [\href{https://journals.aps.org/pra/abstract/10.1103/PhysRevA.109.033106}{Phys. Rev. \textbf{A} 109, 033106 (20…
Multielectron ionization of three-electron strongly driven Ne at high intensities
Samuel James Praill, Georgios Petros Katsoulis, Agapi Emmanouilidou
We extend a recently developed three-dimensional semiclassical model to study double and triple ionization of Ne driven by infrared laser pulses at various intensities. This model…
Formation of singly ionized oxygen atoms from O driven by XUV pulses: a toolkit for the break-up of FEL-driven diatomics
Miles Mountney, Zixu Wang, Florian Trost +5
We formulate a general hybrid quantum-classical technique to describe the interaction of diatomic molecules with XUV pulses. We demonstrate the accuracy of our model in the context…
Quantum versus semi-classical signatures of correlated triple ionization in Dalitz plots
Dmitry K. Efimov, Georgios P. Katsoulis, Tymoteusz RozpÄtkowski +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…
