Abstract

We systematically study the coupling of longitudinal modes (shells) in a carbon nanotube quantum dot. Inelastic cotunneling spectroscopy is used to probe the excitation spectrum in parallel, perpendicular, and rotating magnetic fields. The data is compared to a theoretical model, including coupling between shells based on atomically sharp disorder in the nanotube. The calculated excitation spectra show good correspondence with experimental data.
