Geometric Phase Transitions
D. C. Brody, A. Ritz
A model in statistical mechanics, characterised by the corresponding Gibbs measure, is a subset of the totality of probability distributions on the phase space. The shape of this s…

An Analytical Approach to Lattice Gauge-Higgs Models
T. S. Evans, H. F. Jones, A. Ritz
We describe an application of the linear $\de$-expansion to the calculation of correlation functions in SU(2)-Higgs lattice gauge theory. A significant advantage of the technique i…

A New Approach to QCD Sum Rules and Inclusive Decay
H. F. Jones, A. Ritz, I. L. Solovtsov
We show that renormalization group improvement, making use of analyticity and the structure of the operator product expansion, combined with a non-perturbative expansion method all…
