We perform theoretical calculations to study steady-state electron transport in a double quantum dot, DQD, coupled to a quantized cavity photon field both in resonance and off-resonance regimes considering weak and strong coupling. In the resonant strong coupling regime, photon exchanges between the energy states of the DQD and the cavity are found reflecting multiple Rabi-resonances. The electron occupation of the states and the transport current can be smoothly increased by tuning the cavity-environment coupling strength. Making the system off-resonant, but still in the strong coupling regime, the photon exchange is diminished and the electron occupation of the system and the transport current through it are prominent for high cavity-environment coupling strength. In the weak coupling regime between the DQD and the cavity, the system has almost the same response in the resonant and the off-resonant regimes at high values of the cavity-environment coupling strength. • Photon exchange produced between the energy states of the cavity and the DQD system due to multiple Rabi-resonances in resonant strong coupling regime. • Transport current smoothly increases as cavity-environment coupling is increased in resonance regime strong coupling regime. • Photon exchange diminished in off-resonant strong coupling regime, and the multiple Rabi-resonances are very weak. • Faster electron population and transport current enhanced at high cavity-environment coupling in off-resonant strong coupling regime.
