On Parametric Resonance in Quantum Many-Body System
Y. Tsue, J. da Providencia, A. Kuriyama +1
The dynamics governed by a requantized collective Hamiltonian in the coupled Lipkin model is investigated in the time-dependent variational approach with squeezed state. It is poin…

The su(1,1)-Algebraic Boson Model in the Deformed Boson Scheme
A. Kuriyama, C. Providencia, J. da Providencia +2
Following the deformed boson scheme leading to the su(1,1)-algebra, a certain simple boson system is deformed in the framework of the second Holstein-Primakoff representation. With…

A Possible Boson Realization of Generalized Lipkin Model for Many-Fermion System
A. Kuriyama, C. Providencia, J. da Providencia +2
On the basis of the formalism proposed by three of the present authors (A.K., J.P.and M.Y.), generalized Lipkin model consisting of (M+1) single-particle levels is investigated. Th…
