Abstract:

The transport properties of a wire-dot system coupled to a quantized single photon with linear polarization in a 3D-cavity is theoretically studied using a quantum master equation. The system is also coupled to a photon reservoir, environment. We interplay between the electron-photon coupling, gγ, and the cavity-reservoir coupling, κ, in three cases: κ<gγ, κ=gγ, and κ>gγ. The current peaks due to intraband transitions between the Rabi-resonant states are formed when the electron-photon coupling is dominant, κ<gγ. The broadening of the current peaks depends on the photon polarization and the geometry of the resonant states. It is remarkable that a current plateau is found when κ≥gγ in which the cavity-reservoir is dominant. In this case, the intraband transitions are diminished and the current peaks are not seen.
