Quark spin polarization and spontaneous magnetization in high density quark matter
Y. Tsue, J. da Providencia, C. Providencia +3
By using the Nambu-Jona-Lasinio model with a tensor-type four-point interaction between quarks, it is shown that there exists a possibility of a spin polarized phase in quark matte…
Spin polarization in high density quark matter under a strong external magnetic field
Yasuhiko Tsue, Joao da Providencia, Constanca Providencia +2
In high density quark matter under a strong external magnetic field, possible phases are investigated by using the two-flavor Nambu-Jona-Lasinio model with tensor-type four-point i…
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…
Spin Polarization versus Color-Flavor-Locking in High Density Quark Matter
Y. Tsue, J. da Providencia, C. Providencia +2
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-Jon…
