Electronic transport in carbon nanotube quantum dots

The talk will focus on aspects of electronic transport in CNT quantum dots -- theoretically, but set firmly in an experimental context. Particular emphasis will be given to zero-bias transport, and the evolution of conductance as a function of gate voltage, temperature and dot-lead tunnel couplings. The symmetry-breaking role of spin-orbit coupling will also be discussed; in particular its interplay with the two regimes of SU(4) Kondo physics towards the centres of the Coulomb blockade valleys, which has rather striking implications for experiment.
