    • We emphasize that our proposal differs from other suggested experimental realizations of the 2CK effect [16,17], in that our local degeneracy comes from spin rather than charge or some other two-level system. Our mapping differs from that of [17] in several essential ways: We consider a system sith fixed electron number in what would otherwise be a Coulomb valley, not a charge degeneracy point; our Kondo temperature is set by the charging enregy of a small dot; and we do not requires single-mode coupling between the dot and leads. Our 2CK effect is realized at equilibrium, avoiding decoherence and suppression of 2Ck by voltage-driven current [18].

    • In semiconductor structures, generally D > U. We will assume this here, but relaxing this assumption has no significant impact on our conclusions.
