Beilstein Journal of Nanotechnology, 10, 606–616. https://doi.org/10.3762/bjnano.10.612190-4286https://hdl.handle.net/20.500.11815/1863Publisher's version (útgefin grein)In this work, we theoretically model the time-dependent transport through an asymmetric double quantum dot etched in a two-dimensional wire embedded in a far-infrared (FIR) photon cavity. For the transient and the intermediate time regimes, the current and the average photon number are calculated by solving a Markovian master equation in the dressed-states picture, with the Coulomb interaction also taken into account. We predict that in the presence of a transverse magnetic field the interdot Rabi oscillations appearing in the intermediate and transient regime coexist with slower non-equilibrium fluctuations in the occupation of states for opposite spin orientation. The interdot Rabi oscillation induces charge oscillations across the system and a phase difference between the transient source and drain currents. We point out a difference between the steady-state correlation functions in the Coulomb blocking and the photon-assisted transport regimes.606-616eninfo:eu-repo/semantics/openAccessElectron transportInteractionsPhoton cavityPhoton-dressed electron statesTime dependentOscillationsMarkov processesRafeindirLjóseindirTímiSveiflufræðiMarkovferliSkammtafræðiRafsegulfræðiinfo:eu-repo/semantics/articleBeilstein Journal of Nanotechnology10.3762/bjnano.10.61
