概要

• 論文の詳細を見る

• The two-level pairing model obeying the su (2) ⊗ su (2)-algebra, which was discussed in a previous paper, is re-formed in the framework of the su (1, 1) ⊗ su (1, 1)-algebra in the Schwinger boson representation. With the aid of the MYT mapping method, the Schwinger boson representation is reduced to the Holstein-Primakoff boson representation, which is expressed in terms of two kinds of bosons. Further, with the aid of the squeezed coherent state, the classical counterpart is obtained.
