Query: Electron-vibron coupling in suspended nanotubes   We consider the electron-vibron coupling in suspended nanotube quantum dots.
Modelling the tube as an elastic medium, we study the possible coupling
mechanism for exciting the stretching mode in a single-electron-transistor
setup. Both the forces due to the longitudinal and the transverse fields are
included. The effect of the longitudinal field is found to be too small to be
seen in experiment. In contrast, the transverse field which couple to the
stretching mode via the bending of the tube can in some cases give sizeable
Franck-Condon factors. However, the length dependence is not compatible with
recent experiments [Sapmaz et al. cond-mat/0508270].
