Temperature dependent nonequilibrium magneto-transport in a correlated polar single molecular transistor with quantum dissipation

Abstract

Quantum magneto-transport in a dissipative single molecular transistor is investigated at finite temperature in the presence of electron correlation and electron-phonon interaction within the framework of the Anderson-Holstein-Caldeira-Leggett Hamiltonian. The electron-phonon interaction and dissipation are dealt with by canonical transformations and the Coulomb correlation is treated at the mean-field level. The transport properties such as spectral function, tunneling current, differential conductance, and spin polarization are determined using the Keldysh method.
