Phonon-Assisted Electronic Transport through Double Quantum Dot System Coupled to Ferromagnetic Leads

Phonon-assisted electronic tunneling is studied through a double quantum dot coupled in parallel to ferromagnetic electrodes. The currentvoltage characteristics for the system are derived within the nonequilibrium Green function technique based on equation of motion. It is found that additional phonon-induced resonance peaks appear in the spectral function on both sides of the main resonances corresponding to the quantum dot energy levels. It is shown that the molecular-like resonances are reproduced in the phonon side bands in the dierential conductance. A signicant phonon-induced enhancement of tunnel magnetoresistance as well as tunnel magnetoresistance oscillations are also predicted
