Stochastic Geometric Aspects of Some Quantum Spin Chains,We discuss some rigorous results that were recently obtained using a new Poisson integral representation for the Gibbs kernel of a class of antiferromagnetic quantum spin models.

Homogeneity in the Ground State of the Two-Dimensional Falicov-Kimball Model,hysical interpretations of this model. We will use the interpretation in which one thinks of the hopping fermions as electrons and the static particles as nuclei. The Hamiltonian is.where .. and .. are creation and annihilation operators for the electrons, .(.) = 1 if there is a nuclei at . and .(.) = 0 if there is not.
