In a series of recent experiments anomalously large probabilities of laser-induced double ionization of the He atom have been observed. In this letter we analyse the clearest observation of this phenomenon, over a signal range of many orders of magnitude, by Walker et al. The analysis is carried out using a newly developed intense-field many-body S-matrix theory. For the first time good agreement between the experimental data and a theory is found. It is shown that the dominant mechanism behind… 

An electron of helium atom under a high-intensity laser field

We scrutinize the behavior of eigenvalues of an electron in a helium (He) atom as it interacts with electric field directed along the z-axis and is exposed to linearly polarized intense laser field

Directional correlation in direct and sequential double ionization of model atoms.

Direction dependence in the time development of spatial wavefunctions, which includes jet formation, for two-electron model atoms exposed to intense laser fields is discussed, and the importance of the electron-Electron repulsion contribution to the competing processes is investigated.

Strong field double ionization: what is under the ‘knee’?

Both uncorrelated (‘sequential’) and correlated (‘nonsequential’) processes contribute to the double ionization of the helium atom in strong laser pulses. The double ionization probability has a

Many-electron strong-field physics

Double and multiple ionisation cannot be understood without the contribution of a non-sequential mechanism, which is due to electron–electron correlation. This paper discusses the experimental
