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

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.
