Abstract

The isotropic quantum Heisenberg antiferromagnet at T�0 is studied using the renormalization group method for perturbation expansion of the Dyson-Maleev spin wave model in the inverse of the spin size S. The exponent n which characterizes the correlations is given in powers of s as � 2e2. The result does not agree with that of non-linear cr-model in two dimension.
