Two-color phase-of-the-phase spectroscopy applied to nonperturbative electron-positron pair production in strong oscillating electric fields
J. Braß, R. Milbradt, S. Villalba-Chávez +2
Production of electron-positron pairs from vacuum in strong bichromatic electric fields, oscillating in time with a fundamental frequency and its second harmonic, is studied. Stron…
Resonant single-photon double ionization driven by combined intra- and interatomic electron correlations
A. Eckey, A. B. Voitkiv, C. Müller
Double ionization of an atom by single-photon absorption in the presence of a neighbouring atom is studied. The latter is, first, resonantly photoexcited and, afterwards, transfers…
Dynamic two-center resonant photoionization in slow atomic collisions
A. B. Voitkiv, C. Müller, S. F. Zhang +1
An additional channel opens for photoionization of atom by an electromagnetic field if it traverses a gas of atoms resonantly coupled to this field. We show that this chann…
Resonant electron scattering and dielectronic recombination in two-center atomic systems
A. Eckey, A. Jacob, A. B. Voitkiv +1
Electron scattering and dielectronic recombination with an ion in the presence of a neighboring atom is studied. The incident electron is assumed to be captured by the ion, leading…
