Institut fu¨r Theoretische Physik A, RWTH Aachen, 52056 Aachen, Germany(Dated: November 18, 2010)We demonstrate single electron addition to different strands of a carbon nanotube rope. Anti-crossings of anomalous conductance peaks occur in quantum transport measurements through theparallel quantum dots forming on the individual strands. We determine the magnitude and thesign of the hybridization as well as the Coulomb interaction between the carbon nanotube quantumdots, finding that the bonding states dominate the transport. In a magnetic field the hybridizationis shown to be selectively suppressed due to spin effects.
