Possibility of two-channel orbital Kondo "spin" 1/2 conductance in a quantum dot

Mesoscale and Nanoscale Physics 2009-11-07 v2 Strongly Correlated Electrons

Abstract

We propose that two-channel orbital Kondo ``spin'' 1/2 conductance can be measured in a quantum dot at Coulomb Blockade with an odd number of electrons with contacts in a pillar configuration, if an orthogonal magnetic field induces an appropriate level crossing. At the zero-temperature strong coupling fixed point the conductance reaches the unitarity limit with a non-Fermi liquid sqrt(T)-law.
