标题： Tensor condensate accompanied by chiral transition in a strong magnetic field

摘要： 我们研究在强磁场存在下，有限温度和密度的(2+1)-味Nambu-Jona-Lasinio模型中的张量凝聚和手征凝聚。张量凝聚的出现归因于四费米子相互作用。结果显示，发生向张量凝聚相变需要足够大的化学势。此外，我们研究了张量凝聚与自旋极化之间的关系，这解释了从手征凝聚相到张量凝聚相转变过程中自旋极化的振荡行为。 显示英文摘要

摘要： We investigate tensor condensates and chiral condensates in the (2+1)-flavor Nambu-Jona-Lasinio model at finite temperature and density in the presence of a strong magnetic field. The emergence of the tensor condensate is attributed to the four-fermion interaction. It is shown that a sufficiently large chemical potential is necessary for the occurrence of a phase transition towards tensor condensate. Furthermore, we investigate the correlation between tensor condensate and spin polarization, which accounts for the oscillatory behavior of the spin polarization during the transition from the chiral condensate to tensor condensate phase.
