英文摘要	We have investigated the current for the system of vibrating quantum dot irradiated with a rotating magnetic field and an oscillating magnetic field by nonequilibrium Green's function. The rotating magnetic field rotates with the angular frequency omega(r) around the z-axis with the tilt angle 0, and the time-oscillating magnetic field is located in the z-axis with the angular frequency omega. Different behaviors have been shown in the presence of electron-phonon interaction (EPI) which plays a significant role in the transport. The current displays asymmetric behavior as the source-drain bias eV = 0. novel side peaks or shoulders can be found due to the phonon absorption and emission procedure, and the negative differential resistance becomes stronger as the parameter g increases. Furthermore, the strong EPI also destroys the quasiperiodic oscillations of current in the region mu(0)B(1) > 2.5 Delta. The electron transport properties are also significantly influenced by the linewidth function Gamma. (C) 2010 Elsevier B.V. All rights reserved.
