    "abstract": "Aspects of the phase change of the two-level pairing model are investigated\nin the semi-classical treatment by using the variational approch with the\nmixed-mode coherent state. In the classical limit, $hbar \\to 0$, the sharp\nphase transition appears and the two phases exist in the region where the force\nstrength is larger than a certain critical value. However, it is shown that, in\nthe semi-classical treatment, the above-mentioned behavior of the phase change\ndisappears in the analytical and the numerical treatments. As a result, new\nunderstanding about aspects of the phase change in this model is given.",
