Abstract

A possibility of spontaneous magnetization in high density symmetric quark matter is investigated using the NJL type effective model of QCD by means of an effective potential with respect to an auxiliary field. It is shown that the quark ferromagnetic condensate has non-vanishing value at high baryon density due to the tensor-type four-point interaction between quarks. Subject Index: 230
高密度夸克物质中夸克铁磁化的有效势法
利用QCD的NJL型有效模型,利用辅助场的有效势,研究了高密度对称夸克物质自发磁化的可能性。结果表明,由于夸克之间存在张量型四点相互作用,夸克铁磁凝聚在高重子密度下具有不消失值。科目索引:230
