Query: Signatures of the Current Blockade Instability in Suspended Carbon
  Nanotubes   Transport measurements allow sensitive detection of nanomechanical motion of
suspended carbon nanotubes. It has been predicted that when the
electro-mechanical coupling is sufficiently large a bistability with a current
blockade appears. Unambiguous observation of this transition by current
measurements may be difficult. Instead, we investigate the mechanical response
of the system, namely the displacement spectral function; the linear response
to a driving; and the ring-down behavior. We find that by increasing the
electro-mechanical coupling the peak in the spectral function broadens and
shifts at low frequencies while the oscillator dephasing time shortens. These
effects are maximum at the transition where non-linearities dominate the
dynamics. These strong signatures open the way to detect the blockade
transition in devices currently studied by several groups.
