概要

• 論文の詳細を見る

• Properties of the phase change of the two-level pairing model are investigated in the semi-classical treatment by using the variational approach with a mixed-mode coherent state. In the classical limit, &plnkv; →0, a sharp phase transition appears, and the two phases exist in the region where the force strength is larger than a certain critical value. However, it is shown that, in the semi-classical treatment, the above-mentioned behavior of the phase change disappears in both analytical and numerical treatments. This leads to a new understanding of the properties of the phase change in this model.
