Abstract:

New Hartree-Fock ground states are shown to result in the two-impurity Anderson model when coupled to boson-like interactions. The new states are asymmetric in both charge and spin in the two sites and exhibit the two types corresponding to the different exchange mechanisms. This situation in which two identical atoms behave as two unbalanced centers may have a variety of applications in condensed-matter physics such as valence fluctuations in solids.
