A Cluster Expansion for Dipole Gases
arXiv:cond-mat/9809023 · doi:10.1016/S0378-4371(98)00055-7
Abstract
We give a new proof of the well-known upper bound on the correlation function of a gas of non-overlapping dipoles of fixed length and discrete orientation working directly in the charge representation, instead of the more usual sine-Gordon representation.
