A Role of the Quasiparticle in the Conservation of the Fermion Number    [PDF]

Y. Tsue, C. Providencia, J. da Providencia, M. Yamamura

The role of the "quasiparticle" introduced in last paper by the present authors is discussed. It serves as a guide for the deformation of the Cooper-pair in the BCS-Bogoliubov approach. As an illustrative example, a certain case is treated. This case produces the su(1,1)-like behavior in the su(2)-algebraic many-fermion system.
