Spin-spin correlation in some frustrations models
Abstract
Gauge-invariant spin correlation functions are calculated by making low temperature expansion in two types of regular layered frustration models on a square lattice whose unit layer contains a single line or two neighboring lines of frustration. The results suggest that the layered model of single frustration lines has no long-range order at low temperatures while the other does, both irrespective of the spacing of frustration lines.
