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

2011/8/4
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...
Molecular imaging using high-order harmonic generation and above-threshold ionization
above-threshold high-order harmonic
2011/9/1
Accurate molecular imaging via high-order harmonic generation relies on comparing the harmonic emission from a molecule and an adequate reference system. However, an ideal reference atom with the same...
Controlling double ionization of atoms in intense bichromatic laser pulses

2010/11/17
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...
Atomic Ionization by keV-scale Pseudoscalar Dark Matter Particles
Atomic Ionization keV-scale Pseudoscalar Dark Matter Particles
2010/3/16
Using the relativistic Hartree-Fock approximation, we calculate the rates of atomic ionization by absorption of pseudoscalar particles in the mass range from 10 to $\sim$ 50 keV. We present numerical ...
Self Ionization Probabilities Following De-excitation Decay of K-Shell Vacancy in Atoms Z = 10--80
Atomic properties Auger vacancy cascades ion charge state distributions
2010/4/12
The average number of ejected electrons and the probability of ion charge state distributions following K-shell ionization in atoms from Z = 10 to Z = 80 were calculated. Monte Carlo simulation techni...
