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…

Deformed Boson Scheme Stressing Even-Odd Boson Number Difference. I

A. Kuriyama, C. Providencia, J. da Providencia +2

An idea of the deformed boson scheme developed by the present authors is applied to the case of boson-pair coherent state. In this state, even and odd boson number difference is st…

Variational Approach to the Dynamics of Bose-Einstein Condensates.I --Variational Ansatz and Quantum Dynamics--

Y. Tsue, D. Vautherin, T. Matsui

Variational method is applied to describe Bose-Einstein condensates (BEC) interacting via a pseudo-potential, taking into account quantum fluctuations around the mean field by the…

On A Possible Scheme of q-Deformation of Many-Boson Systems in Time-Dependent Variational Method

A. Kuriyama, C. Providencia, J. da Providencia +2

A possible scheme of q-deformation, which was recently developed by the present authors, is reviewed by stressing the starting idea.
