Abstract: We investigate strong mechanical feedback for a single electron tunneling (SET) device coupled to an underdamped harmonic oscillator in the high-frequency case, when the mechanical energy of the oscillator exceeds the tunnel rate, and for weak coupling. In the strong feedback regime, the mechanical oscillations generated by the telegraph signal from the SET device in their turn modify the electric current. In contrast to the previously published results for the low frequencies, the current noise is not enhanced above the Poisson value.
