transport through suspended carbon-nanotube quantum dots    [PDF]

We investigate the electronic transport through a suspended carbon-nanotube
quantum dot. In the presence of a magnetic field perpendicular to the nanotube
and a nearby metallic gate, two forces act on the electrons: the Laplace and
the electrostatic force. They both induce coupling between the electrons and
the mechanical transverse oscillation modes. We find that the difference
between the two mechanisms appears in the cotunneling current.
