Résumé:
By combining exact diagonalization with scaling method, we show that it is possible to realize two-channel spin-1/2 Kondo (2CK) conductance in a quantum dot at Coulomb Blockade, with an odd number of electrons and with contacts in a pillar configuration, as an applied orthogonal magnetic field B is tuned at an appropriate level crossing.
