Spin Polarization versus Color-Flavor-Locking in High Density Quark Matter
arXiv:1409.6383 · doi:10.1093/ptep/ptu172
Abstract
It is shown that spin polarization with respect to each flavor in three-flavor quark matter occurs instead of the color-flavor locking at high baryon density by using the Nambu-Jona-Lasinio model with four-point tensor-type interaction. Also, it is indicated that the order of phase transition between the color-flavor locked phase and the spin polarized phase is the first order by means of the second order perturbation theory.
