Quantum many-body systems interacting with electromagnetic fields are candidates for quantum interfaces in communication and nanoplasmonic applications. We will investigate the coupling of an electronic current in a nanoconstriction to a lightinduced plasmonicexcitation using both model-based approaches and numerical simulations aimed at realistic geometries. The combination of strong non-equilibrium and quantum many-body aspects requires the development of new methods to take into account the long-range Coulomb interaction and screening. The goal is to achieve a better understanding of the plasmon-enhanced coupling mechanism between light and electronic degrees of freedom. This concerns especially the geometrical details determining the coupling as well as aspects like quantum entanglement transfer.
