Query: Probing nonlinear mechanical effects through electronic currents: the
  case of a nanomechanical resonator acting as electronic transistor   We study a general model describing a self-detecting single electron
transistor realized by a suspended carbon nanotube actuated by a nearby
antenna. The main features of the device, recently observed in a number of
experiments, are accurately reproduced. When the device is in a low
current-carrying state, a peak in the current signals a mechanical resonance.
On the contrary, a dip in the current is found in high current-carrying states.
In the nonlinear vibration regime of the resonator, we are able to reproduce
quantitatively the characteristic asymmetric shape of the current-frequency
curves. We show that the nonlinear effects coming out at high values of the
antenna amplitude are related to the effective nonlinear force induced by the
electronic flow. The interplay between electronic and mechanical degrees of
freedom is understood in terms of an unifying model including in an intrinsic
way the nonlinear effects driven by the external probe.
