Local Franck-Condon factors in suspended carbon nanotubes quantum dots

Electron and vibron coupling in suspended carbon nanotube quantum dots is considered, analyzing the crucial role of spatial fluctuations of the electronic density. Space-dependent Franck-Condon factors are discussed, and ensuing marked effects on transport are shown in comparison with recent measurements. Predictions on the spatial conductance pattern, obtained by scanning the system with an STM tip will be presented.
