The phase portrait of dense quark matter is investigated within the (3 + 1)-dimensional Nambu—Jona-Lasinio model taking the isospin and chiral-isospin asymmetries in quarks into account. It is shown that the chiral-isospin chemical potential contributes to the generation of the phase with charged pion condensation.

Nambu-Jona-Lasinio模型中具有同位旋和手性-同位旋不对称性的热密集夸克物质中的离子冷凝

在(3 + 1)维Nambu-Jona-Lasinio模型中,考虑了夸克中的同位旋和手性-异旋旋不对称性,研究了稠夸克物质的相图。结果表明,手性异构体的化学势有助于带电离子缩合的相的产生。
