Semi-Classical Approach to the Two-Level Pairing Model --Various Aspects of Phase Change--
Y. Tsue, C. Providencia, J. da Providencia +1
Aspects of the phase change of the two-level pairing model are investigated in the semi-classical treatment by using the variational approch with the mixed-mode coherent state. In…
The Lipkin Model in Many-Fermion System as an Example of the su(1,1) times su(1,1)-Algebraic Model
C. Providencia, J. da Providencia, Y. Tsue +1
Following the idea, recently, proposed by the present authors for the two-level pairing model, the Lipkin model is reexamined. It is a natural generalization of the method already…
A Note on the Two-Level Pairing Model Obeying the su(2)*su(2)-Algebra
C. Providencia, J. da Providencia, Y. Tsue +1
The two-level pairing model obeying the su(2)*su(2)-algebra, which was discussed in the previous paper, is re-formed in the framework of the su(1,1)*su(1,1)-algebra in the Schwinge…
