If you have a question about this talk, please contact Dr Jonathan Keeling. The low-energy behaviour of quantum dots coupled to metallic leads is commonly associated with a single ‘active’ dot level, and hence with the spin-1/2 Kondo efect. But this is not ubiquitous: if several dot levels are relevant to charge transport, higher spin Kondo efects may arise, and have been observed experimentally. This talk will discuss a rather general model for a two-level correlated quantum dot, studied largely via RG. Particular consideration will be given to the spin-1 and spin-1/2 Kondo regimes which occur on sweeping the dot levels through the Fermi level by tuning a gate voltage; to the nature of the resultant quantum phase transition between the regimes arising in a two-lead, one-channel setup; and to comparison to experiment. Time permitting, I may also discuss some aspects of SU(4) Kondo physics in carbon nanotube quantum dots. This talk is part of the Theory of Condensed Matter series.
