title: Vibrational coherences in single electron tunneling through nanoscale oscillators.
abstract: Charging a nanoscale oscillator by single electron tunneling leads to an effective double-well potential due to image charges. We combine exact numerical diagonalizations with generalized master equations and show that the resulting quantum tunneling of the mechanical degree of freedom can be visualized in the electronic current noise spectrum.
