Название: Convergent Expansions for Asymptotically Degenerate Inverse Correlation Lengths of Classical Lattice Spin Systems
Автор: O'Carroll M.
We obtain convergent expansions for the inverse correlation length associated with various spin-spin correlation functions for some weakly coupled multicom-ponent classical lattice spin systems. In terms of the lattice quantum field theory associated with the models the expansions provide a convergent perturbation
theory for particle masses which are asymptotically degenerate in the limit of zero coupling.
