Model for atomic dielectric response in strong, time-dependent laser fields

Ionization of atomic hydrogen in strong infrared laser fields

We have used the matrix iteration method of Nurhuda and Faisal [Phys. Rev. A 60, 3125 (1999)] to treat ionization of atomic hydrogen by a strong laser pulse. After testing our predictions against a variety of previous calculations, we present ejected-electron spectra as well as angular distributions for few-cycle infrared laser pulses with peak intensities of up to 1015 W/cm2. It is shown that ...

Ultrarelativistic quasiclassical wave functions in strong laser and atomic fields

Abstract The problem of an ultrarelativistic charge in the presence of an atomic and a plane-wave field is investigated in the quasiclassical regime by including exactly the effects of both background fields. Starting from the quasiclassical Green’s function obtained in [Phys. Lett. B 717, 224 (2012)], the corresponding inand out-wave functions are derived in the experimentally relevant case of...

DMTDHF: A full dimensional time-dependent Hartree-Fock program for diatomic molecules in strong laser fields

We present the DMTDHF package, which investigates the non-perturbative electronic dynamics of diatomic molecules subjected to strong external laser fields by the fully propagated time-dependent Hartree–Fock theory. The package uses the prolate spheroidal coordinates, together with the finiteelement method and discrete-variable representation, while short iterative Lanczos algorithm is employed ...

The time-dependent two-particle reduced density matrix method: LiH in strong laser fields

Time-dependent Model Calculations for the Molecular Hydrogen Ion in a Strong Ultra-short Laser Pulse

We have revisited the problem of a hydrogen molecular ion in the presence of a short intense laser field. Our approach for time-propagation the initial state subject to the Schrödinger equation is similar to that presented by Kulander et al. [1]. A common simplification to the full problem is the reduction to one dimension with two degrees of freedom, one for the nuclear separation (R) and one ...
