Superradiance in transport through ensemble of double quantum dots

We theoretically study the transport through an ensemble of double quantum dots (DQDs) fabricated in a microwave cavity. The DQDs are coupled to a common eld of photon by coupling constant λ, whereas the photons escape from the cavity with the rate of ph. When ph ≥ λ, a photon emission from the DQDs creates an entanglement among electrons in the DQDs, which enhances the rate of the subsequent emission (superradiance). We propose a transport experiment to observe the superradiance using a sequence of voltage pulses.
