具有复共轭质量极的动力学夸克模型的热力学不稳定性

Thermodynamic instabilities in dynamical quark models with complex conjugate mass poles

Sanjin Benić, David Blaschke, Michael Buballa

摘要:

我们证明了用复共轭质量极表示夸克传播子的动力学夸克模型的CJT热力学势不可避免地表现出热力学不稳定性。我们发现,夸克扇区的最小耦合的Polyakov圈势可以强烈抑制,但不能完全消除这种不稳定性。这种普遍效应在协变、手征对称、有效的夸克模型的框架中得到了明确的证明。

英文摘要:

We show that the CJT thermodynamic potential of dynamical quark models with a quark propagator represented by complex conjugate mass poles inevitably exhibits thermodynamic instabilities. We find that the minimal coupling of the quark sector to a Polyakov loop potential can strongly suppress but not completely remove such instabilities. This general effect is explicitly demonstrated in the framework of a covariant, chirally symmetric, effective quark model.
