Útdráttur:We show that a Rabi-splitting of the states of strongly interacting electrons in parallel quantum
dots embedded in a short quantum wire placed in a photon cavity can be produced by either the
para- or the dia-magnetic electron-photon interactions when the geometry of the system is properly
accounted for and the photon field is tuned close to a resonance with the electron system. We
use these two resonances to explore the electroluminescence caused by the transport of electrons
through the one- and two-electron ground states of the system and their corresponding conventional
and vacuum electroluminescense as the central system is opened up by coupling it to external leads
acting as electron reservoirs. Our analysis indicates that high-order electron-photon processes are
necessary to adequately construct the cavity-photon dressed electron states needed to describe both
types of electroluminescence.
