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…
