We show how the switching-on of an electron transport through a system of twoparallel quantum dots embedded in a short quantum wire in a photon cavity cantrigger coupled Rabi and collective electron-photon oscillations. We select theinitial state of the system to be an eigenstate of the closed system containingtwo Coulomb interacting electrons with possibly few photons of a single cavitymode. The many-level quantum dots are described by a continuous potential. TheCoulomb interaction and the para- and dia-magnetic electron-photon interactionsare treated by exact diagonalization in a truncated Fock-space. To identify thecollective modes the results are compared for an open and a closed system withrespect to the coupling to external electron reservoirs, or leads. Wedemonstrate that the vacuum Rabi oscillations can be seen in transportquantities as the current in and out of the system.
