    "abstract": "We provide a detailed quantum treatment of the spectral characteristics and\nof the dynamics of nondispersive two-electron wave packets along the\nperiodically driven, collinear frozen planet configuration of helium. These\nhighly correlated, long-lived wave packets arise as a quantum manifestation of\nregular islands in a mixed classical phase space, which are induced by\nnonlinear resonances between the external driving and the unperturbed dynamics\nof the frozen-planet configuration. Particular emphasis is given to the\ndependence of the ionization rates of the wave packet states on the driving\nfield parameters and on the quantum mechanical phase space resolution, preceded\nby a comparison of 1D and 3D life times of the unperturbed frozen planet.\nFurthermore, we study the effect of a superimposed static electric field\ncomponent, which, on the grounds of classical considerations, is expected to\nstabilize the real 3D dynamics against large (and possibly ionizing) deviations\nfrom collinearity.",
