| Abstract: | This paper proves the equivalence between the one-dimensional Heisenberg antiferromagnet model in the semiclassical limit of large-but-finit S and O(3) nonlinear sigma model. Therefore, The author get some qualities of Heisenberg antiferromagnet,and predict the dynamic mass generation by the Neel magnon. 6refs. |
