Geometric expansion of the log-partition function of the anisotropic Heisenberg model
Daniel Gandolfo, Suren Poghosyan, Jean Ruiz
We study the asymptotic expansion of the log-partition function of the anisotropic Heisenberg model in a bounded domain as this domain is dilated to infinity. Using the Ginibre's r…

Abstract cluster expansion with applications to statistical mechanical systems
Suren Poghosyan, Daniel Ueltschi
We formulate a general setting for the cluster expansion method and we discuss sufficient criteria for its convergence. We apply the results to systems of classical and quantum par…
