Three-electron correlations in strong laser field ionization

Strong field processes involving several active electrons reveal unambiguous dynamical signatures of the Pauli principle importance even in nonrelativistic regime. We exemplify this statement studying three model atoms interacting with strong pulsed radiation, using an ab-initio time-dependent Schrödinger equation on a grid. In our restricted dimensionality we are able to analyze momenta correlations outgoing Dalitz plots. The different symmetries electronic wavefunctions, directly related initial state spin components, appear clearly visible.
