摘要:

采用双味Nambu-Jona-Lasinio模型,计算了零温度、有限夸克化学势条件下夸克物质中夸克间赝矢量型四点相互作用引起的自发磁化率和磁化率.结果表明,手征凝聚和自旋极化凝聚共存于夸克化学势的一个狭窄区域内。同时还表明,在这个狭窄的区域内,出现了自发磁化。此外,在自旋极化阶段,由于夸克的正能量的磁化率进行了评估。

英文摘要:

Spontaneous magnetization and magnetic susceptibility originated from the pseudovector-type four-point interaction between quarks are calculated in quark matter with zero temperature and finite quark chemical potential by using the two-flavor Nambu-Jona-Lasinio model. It is shown that both the chiral condensate and spin polarized condensate coexist in a narrow region of the quark chemical potential. And then, it is also shown that, in this narrow region, the spontaneous magnetization appears. Also, the magnetic susceptibility due to quarks with the positive energy is evaluated in the spin polarized phase.
