The strong field approximation within a Faddeev-like formalism for laser-matter interactions
Yu. Popov, A. Galstyan, F. Mota-Furtado +2
We consider the interaction of atomic hydrogen with an intense laser field within the strong-field approximation. By using a Faddeev-like formalism, we introduce a new perturbative…
Modelling laser-atom interactions in the strong field regime
A. Galstyan, Yu. V. Popov, F. Mota-Furtado +5
We consider the ionisation of atomic hydrogen by a strong infrared field. We extend and study in more depth an existing semi-analytical model. Starting from the time-dependent Schr…
Ionization and excitation of the excited hydrogen atom in strong circularly polarized laser fields
J. H. Bauer, Francisca Mota-Furtado, Patrick F. O'Mahony +2
In the recent work of Herath et al. [Phys. Rev. Lett. 109, 043004 (2012)] the first experimental observation of a dependence of strong-field ionization rate on the sign of the magn…
Explicit schemes for time propagating many-body wavefunctions
Ana Laura Frapiccini, Aliou Hamido, Sebastian Schröter +6
Accurate theoretical data on many time-dependent processes in atomic and molecular physics and in chemistry require the direct numerical solution of the time-dependent Schrödinger…
Effects of nonzero photon momentum in (γ,2e) processes
Alexander G. Galstyan, Ochbadrakh Chuluunbaatar, Yuri V. Popov +1
We study the effects of nonzero photon momentum on the triply-differential cross section for (γ,2e) processes. Due to the low value of the photon momentum, these effects are weak a…
Time scaling with efficient time-propagation techniques for atoms and molecules in pulsed radiation fields
Aliou Hamido, Johannes Eiglsperger, Javier Madroñero +4
We present an ab initio approach to solve the time-dependent Schrödinger equation to treat electron and photon impact multiple ionization of atoms or molecules. It combines the alr…
Spectral data for doubly excited states of helium with non-zero total angular momentum
Johannes Eiglsperger, Moritz Schönwetter, Bernard Piraux +1
A spectral approach is used to evaluate energies and widths for a wide range of singlet and triplet resonance states of helium. Data for total angular momentum is prese…
Representation of a complex Green function on a real basis: I. General Theory
Robin Shakeshaft, Bernard Piraux
When the Hamiltonian of a system is represented by a finite matrix, constructed from a discrete basis, the matrix representation of the resolvent covers only one branch. We show ho…
Two--Electron Atoms in Short Intense Laser Pulses
Armin Scrinzi, Bernard Piraux
We discuss a method of solving the time dependent Schrodinger equation for atoms with two active electrons in a strong laser field, which we used in a previous paper [A. Scrinzi an…
