Quasi-state decompositions for quantum spin systems

Condensed Matter 2008-02-03 v2

Abstract

I discuss the concept of quasi-state decompositions for ground states and equilibrium states of quantum spin systems. Some recent results on the ground states of a class of one-dimensional quantum spin models are summarized and new work in progress is presented. I also outline some challenging open problems and conjectures.
