Magneto-transport in an interacting single molecular transistor using Anderson-Holstein model

Abstract

We study the effect of an external magnetic field and electron-phonon interaction on the quantum transport through a molecular electronic device which consists of a strongly interacting quantum dot coupled to metallic leads with tunnel barriers. We model the system by a single-level symmetric Anderson-Holstein model which is solved by using Spectral density approximation method at finite temperature. We use a modified Gaussian ansatz for the spectral function to calculate the charge current and Spin Polarization.
