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…
Note on the Time Dependent Variational Approach with Quasi-Spin Squeezed State for Pairing Model
Y. Tsue, H. Akaike
A simple many-fermion system in which there exists N identical fermions in a single spherical orbit with pairing interaction is treated by means of the time-dependent variational a…
Deformed Boson Scheme Stressing Even-Odd Boson Number Difference. III
A. Kuriyama, C. Providencia, J. da Providencia +2
A basic idea is proposed for extending the formalism of Part (II) of the series of our paper to the case of the parameter-dependent deformation. It is stressed that, through this e…
Deformed Boson Scheme Stressing Even-Odd Boson Number Difference. II
A. Kuriyama, C. Providencia, J. da Providencia +2
The boson-pair coherent state developed in Part (I) is generalized to the case in which the state is a mixture of even-boson and odd-boson number states. A general framework is sho…
