A possible framework of the Lipkin model obeying the su(n)-algebra in arbitrary fermion number. I --- The su(2)-algebras extended from the conventional fermion-pair and determination of the minimum weight states ---
Yasuhiko Tsue, Constanca Providencia, Joao da Providencia +1
The minimum weight states of the Lipkin model consisting of n single-particle levels and obeying the su(n)-algebra are investigated systematically. The basic idea is to use the su(…

New boson realization of the Lipkin model obeying the su(2)-algebra
Y. Tsue, C. Providencia, J. da Providencia +1
New boson representation of the su(2)-algebra proposed by the present authors for describing the damped and amplified oscillator is examined in the Lipkin model as one of simple ma…
