A Role of the Quasiparticle in the Conservation of the Fermion Number
arXiv:1206.1645 · doi:10.1143/PTP.128.717
Abstract
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.
