TL;DR: An experiment that uses Auger electron angular emission patterns from molecular nitrogen after inner-shell ionization as an ultrafast probe of hole localization shows that observation of symmetry breaking (localization) or preservation (delocalization) depends on how the quantum entangled Bell state created by Auger decay is detected by the measurement.

TL;DR: In this paper, it was shown that the inversion symmetry can be broken by absorption of a linearly polarized photon, which itself has inversion symmetric symmetry, which is the result of the entanglement between symmetric and antisymmetric states resulting from autoionization.

TL;DR: State-of-the-art one-electron multiple scattering and partially correlated random phase approximation calculations are in good agreement with many, but not all, aspects of the experimental data.

TL;DR: By solving the two-level time-dependent Schrödinger equation, it is shown that an interference between the net-two-photon and the one- photon transition creates localized electrons which subsequently ionize.

TL;DR: In this article, single and double ionization of helium by 1GeV/nucleon U{sup 92+} impact was explored in a kinematically complete experiment, where cross sections, emission characteristics of ions and electrons as well as momentum balances were quantitatively discussed in terms of photoionization of the atom in this broadband, ultrashort virtual photon field.
