Boson Realization of the su(3)-Algebra. III
C. Providencia, J. da Providencia, Y. Tsue +1
Following the basic idea developed in (I), the su(3)-model presented by Elliott is investigated. A method for constructing the orthogonal set, in which the angular momenta are good…
Boson Realization of the su(3)-Algebra. IV
C. Providencia, J. da Providencia, Y. Tsue +1
On the basis of the Schwinger boson representation for the Elliott model developed in (III), the Holstein-Primakoff representation for the su(3)-algebra is presented. The basic ide…
Effects of mode-mode and isospin-isospin correlations on domain formation of disoriented chiral condensates
N. Ikezi, M. Asakawa, Y. Tsue
The effects of mode-mode and isospin-isospin correlations on nonequilibrium chiral dynamics are investigated by using the method of the time dependent variational approach with squ…
Boson Realization of the su(3)-Algebra. II
C. Providencia, J. da Providencia, Y. Tsue +1
On the basis of the Schwinger boson representation for the Lipkin model developed in (I), the Holstein-Primakoff representation for the su(3)-algebra is presented. Including the sy…
Boson Realization of the su(3)-Algebra. I
C. Providencia, J. da Providencia, Y. Tsue +1
Following a general form for the Schwinger boson representation of the su(M+1) Lipkin model presented in the previous paper, three types of the orthogonal sets characterizing the s…
Effective Potential Study of the Chiral Phase Transition in a QCD-like Theory
Y. Hashimoto, Y. Tsue, H. Fujii
We construct the effective potential for a QCD-like theory using the auxiliary field method. The chiral phase transition exhibited by the model at finite temperature and the quark…
