Dynamics of strong - field photoionization in two dimensions for short - range binding potentials
نویسندگان
چکیده
Photodetachment in an ultrastrong laser field in two spatial dimensions is investigated ab initio. A qualitative behavior of the packet for a short-range binding potential is contrasted with that for a soft-core potential, in particular dynamical effects due to a rescattering of fragments separated from the main packet are demonstrated.

Cold molecules formation by shaping with light the short-range interaction between cold atoms: photoassociation with strong laser pulses
The paper investigates cold molecules formation in the photoassociation of two cold atoms by a strong laser pulse applied at short interatomic distances, which lead to a molecular dynamics taking place in the light-induced (adiabatic) potentials. A two electronic states model in the cesium dimer is used to analyse the effects of this strong coupling regime and to show specific results: i) accel...
متن کاملTHE SPINLESS SALPETER EQUATION AND MESON DYNAMICS
Applying the variational method, the spinless reduced Bethe-Salpeter (RBS) equation is solved for the mesonic systems, and the mass spectra are obtained. The method is applied to the Hamiltonian with the Gaussian and hydrogen-type trial wave functions, and different potential models are examined. The results for the different potentials are in challenge in light mesons, while they are consisten...
متن کاملSingle-photon double ionization of negative hydrogen ions in the presence of a dc electric field
Double photoionization DPI of two-electron systems has been an intriguing subject of research for the past few decades. At least partially responsible for this is the fact that, near the threshold of complete fragmentation, the process allows an analytic description, a rather rare occurrence for the three-body Coulomb problem. The first, entirely classical, theory providing such a description w...
متن کاملEffects of on-center impurity on energy levels of low-lying states in concentric double quantum rings
In this paper, the electronic eigenstates and energy spectra of single and two-interacting electrons confined in a concentric double quantum rings with a perpendicular magnetic field in the presence of on-center donor and acceptor impurities are calculated using the exact diagonalization method. For a single electron case, the binding energy of on-center donor and acceptor impurities ar...
