Thermal effects on photon-induced quantum transport in a single quantum dot

摘要: We theoretically investigate laser induced quantum transport in a two-level dot attached to electric contacts. Our approach, based on nonequilibrium Green function technique, allows include thermal effects the photon-induced and excitonic coherent dynamics. By solving set of coupled integrodifferential equations, involving correlation propagator functions, we obtain photocurrent occupations as time. The characteristic Rabi oscillations are found both photocurrent, with two distinct sources decoherence: incoherent tunneling fluctuations. In particular, for increasing temperature becomes more thermally occupied which shrinks amplitude oscillations, due Pauli blockade. Finally, interplay between photon electron populations, can switch sign time evolves its stationary value be maximized by tunning intensity.
