Abstract
We show that the low-temperature fixed-point behavior of the negative4 Anderson model involves a "charge Kondo effect," where the local pair behaves as a Heisenberg rather than an XY degree of freedom. Interactions of the local pair with the conduction sea generate a highly polarizable Fermi liquid with enhanced linear specific heat and charge and pair susceptibilities.
