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…
The Heisenberg antiferromagnet: an explicitly rotational invariant formulation
J. da Providencia, C. Providencia, M. Brajczewska
A simple derivation of an explicitly rotational invariant Lagrangian describing the dynamics of an antiferromagnetic spin system is presented. The scope of the derived Lagrangian i…
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…
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.
Deformed Boson Scheme including Conventional q-Deformation in Time-Dependent Variational Method. IV
A. Kuriyama, C. Providencia, J. da Providencia +2
Basic idea presented in Parts (I)-(III) for the deformed boson scheme is applied to the case of the su(2)- and su(1,1)-algebras for describing many-body systems consisting of four…
