    • note
    • A very small direct tunneling term between the dots has been added to allow a continuous transition between the AFM singlet and Kondo state in the SBMFT approximation (see Refs. [12, 14]).

    • note
    • For large H, fluctuations are important and the mean field solution gives unphysical vanishing renormalized tunneling couplings leading to divergences in the dot propagators that we regularize by hand. Going beyond mean field would regularize these divergences.
