A possibility of quark spin polarized phase in high density quark matter
Y. Tsue, J. da Providencia, C. Providencia +2
It is shown that the quark spin polarization may occur for each quark flavor by the use of the Nambu-Jona-Lasinio model with a tensor-type four-point interaction between quarks, wh…

New boson realization of the Lipkin model obeying the su(2)-algebra
Y. Tsue, C. Providencia, J. da Providencia +1
New boson representation of the su(2)-algebra proposed by the present authors for describing the damped and amplified oscillator is examined in the Lipkin model as one of simple ma…
