Causality and quantum interference in time-delayed laser-induced nonsequential double ionization
Causality quantum interference time-delayed laser-induced nonsequential double ionization
2011/8/5
Abstract: We perform a detailed analysis of the importance of causality within the strong-field approximation and the steepest descent framework for the recollision-excitation with subsequent tunnelin...
Mechanism of delayed double ionization in a strong laser field

Abstract: When intense laser pulses release correlated electrons, the time delay between the ionizations may last more than one laser cycle. We show that this "Recollision-Excitation with Subsequent I...

Abstract: With quantum calculations, we have investigated the multiphoton nonsequential double ionization of helium atoms in intense laser fields at ultraviolet wavelengths. Very surprisingly, we find...

We consider the classical dynamics of a two-electron system subjected to an intense bichromatic linearly polarized laser pulse. By varying the parameters of the field, such as the phase lag and the r...
Prevalence of different double ionization pathways and traces of three-body collisions in strongly driven Helium
double ionization three-body collisions driven Helium
2010/11/16
We present a unified treatment of the prevalence of different double ionization (DI) pathways as a function of the sum of the final electron energies in strongly driven Helium. We do so as a function...
Electron Impact Double Ionization of Helium from [e, (3-1)e] Experiments}
Double Ionization (e,2e) [e,(3-1)e] Coincidence Detection Electron Impact
2010/4/14
Electron impact double ionization of helium has been observed in an [e,(3-1)e] experiment at an incident electron energy of 200 eV. 110 eV scattered and 10 eV ejected electrons are observed in coincid...
