Abstract

In Chapter 12, we have used Haldane’s mapping to relate the long-wavelength correlations of the quantum Heisenberg antiferromagnet (QHA) in d dimensions to those of the Nonlinear Sigma Model (NLSM) in d+1 dimensions with additional Berry phases. In Chapters 13 and 14, the correlation length ξ for the NLSM was found for d=1,2,3 using the continuum approximation.
