Climbing the entropy barrier: driving the single- towards the multichannel Kondo effect by a weak coulomb blockade of the leads

We study a model proposed recently in which a small quantum dot is coupled symmetrically to several large quantum dots characterized by a charging energy E(c). Even if E(c) is much smaller than the Kondo temperature T(K), the long-ranged interactions destabilize the single-channel Kondo effect and i...
