dc.description.abstract
Interatomic coulombic electron capture is a non-local process involving the environment-assisted attachment of a free electron with implied consequences for various systems. Starting from the established numerical model of quantum confinements in a nanowire, this dissertation sets out to deduce model-independent hypotheses for future investigations of theoretical or experimental nature and develops a generalised adaptation of the model to test whether the effective-two-electron treatment suffices to successfully capture a free electron in the experimentally motivated system of a barium (II) cation engulfed in a Bose-Einstein condensate of neutral rubidium atoms. Appearing associated to differing electronic states of the confinement region, two subprocesses can contrast in spatial preferences and resonant energies. For the investigated range of parameters, the energy levels of these associated states suggest to provide a starting point for a more comprehensive description beyond the particular parameters of an individual model. A rather simple electric dipole-dipole coupled adaptation of the model is then able to successfully show environment assisted electron attachment to a barium (II) cation aided by a surrounding cloud of ultracold rubidium atoms in typical experimental conditions.

The project was financed by Volkswagen-Stiftung through Freigeist Grant No. 89525, and undertaken at Helmholtz-Zentrum Berlin for Energy and Materials.
Additional support has been awarded through a DAMOP travel grant, WE-Heraeus travel grants, and a HZB PhDabroad grant. Moreover, the project profited from scientific exchange within the DAAD RISE Germany, HZB summer student programme and the QTeam project hosted by the bologna.lab at the Humboldt-Universität zu Berlin supported by the BMBF.
