Abstract
We investigate strong mechanical feedback for the single-electron tunneling 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 oscillated by the telegraph signal from the SET in their turn modify the electric current. In contrast to the earlier results for the low frequencies, the current noise in not enhanced above the Poisson value.
