Abstract
We discuss how local moment physics is modified by the presence of int eractions in the conduction sea. Interactions in the conduction sea ar e shown to open up new symmetry channels for the exchange of spin with localized moments. We illustrate this conclusion in the strong-coupli ng limit by carrying out a Schrieffer-Wolff transformation for a local moment in an interacting electron sea, and show that these correction s become very severe in the approach to a Mott transition.
