| Popis: | The anisotropic antiferromagnetic chain at T = 0 is studied using the renormalization group method for the perturbation expansion of the Dyson-Maleev spin wave model in the inverse of the spin 1/S. We show that the momentum shell recursion relations for the anisotropic coupling constants and for 2/S are similar to those of the anisotropic non-linear sigma-model at two dimensions when the temperature T is replaced by 2/S in the antiferromagnetic chain. |
