冷密夸克物质中的多相

Multi Phase in Cold Dense Quark Matter

Song Shi, Juan Liu, Zhu-fang Cui

摘要:

本文利用无质量NJL模型研究了零温、有限化学势和外加磁场下的动态手征对称性破缺。提出了一种对冷态稠密夸克物质相图中的相进行分类的数学方法,并用数学分析的方法确定了能隙方程解之间的多相现象,即在化学势和磁场一定的情况下,可能有两相共存。

英文摘要:

In this article, we study dynamic chiral symmetry breaking at zero temperature, finite chemical potential and external magnetic field with massless NJL model. We have proposed a mathematical method to classify phases in phase diagram of cold dense quark matter, and use mathematical analysis to identify the multi phase phenomenon among solutions for gap equation which means with fixed chemical potential and magnetic field, there could be two phases coexisting.
