概要
- 論文の詳細を見る
Ordering process of the antiferromagnetic Heisenberg model on the triangularlattice is studied. It is strongly suggested that there exists a phase transition bothby a topological analysis of defects and by a Monte Carlo simulation. The phasetransition is attributed to the pair dissociation of a kind of vortices which cor-respond to the topological point defect, 77.(SO(3))=Z..
