We present a detailed study of the ionization probability of H2O induced by a short intense laser pulse. Within the strong-field approximation, we present total and differential ionization probabilities of the water molecule ...

The interaction between positronium and a short laser pulse is studied in the case, where the photon energy is resonant with the 1s → 2p transition energy. Results from a full numerical solution of the time-dependent ...

Above-threshold ionization of atoms by XUV short laser pulses is investigated close to the resonant 1s–2p transitions. Both ab initio TDSE and a theoretical Coulomb–Volkov like theory are used to study the enhancement in ...

We investigate the influence of the Coulomb potential as well as the two center contribution in the angle-resolved photoelectron spectrum, resulting from the single ionization of H[image omitted] molecules by short laser ...

Above-threshold ionization of atoms by XUV short laser pulses with frequencies close to the resonant 1s–2p transition is investigated. We present a theory based on a variational expression using trial wavefunctions for the ...

An explicitly gauge invariant strong field theory is introduced and tested using a model laser-atom interaction. The theory relies on a power series in the target potential. Transitions amplitudes are obtained by using a ...

We present a joint experimental and theoretical study of ionization of argon atoms by a linearly polarized two-color laser field (800 nm, 400 nm). Changing the relative phase between the two colors, the forward-backward ...

Argon photo-electron spectra produced by short-pulse extreme ultraviolet radiation, and with particular emphasis on the two-photon absorption region, is analyzed theoretically. The electromagnetic pulse is modeled to ...

The ionization of atomic hydrogen by an intense laser field resonant with the transition ls-Spo is studied. The intensity of the field is strong enough to make the Rabi oscillations important. The theoretical treatment of ...

We present a detailed study of the ionization probability of H and H$_{2}^{+}$ induced by a short intense laser pulse. Starting from a Coulomb–Volkov description of the process we derive a multipole-like expansion where ...
