Abstract
We report on the successful numerical implementation of an original method for the accurate quantum treatment of helium under electromagnetic driving. Our approach is the first to allow for a description of the highly complex quantum dynamics of this system, in the entire non-relativistic parameter regime, i.e., it provides full spectral and dynamical information on the ionization of the atomic ground state by optical fields, as well as on the dynamics of doubly excited Rydberg states under radiofrequency driving. As a by-product, the non-trivial role of the dimension of configuration space for the field-free dynamics of doubly excited helium is elucidated.
