中性双味稠密QCD中的胶子相和phase diagram

Gluonic phases and phase diagram in neutral two flavor dense QCD

Michio Hashimoto, V. A. Miransky

摘要:

对冷中性二味稠密夸克物质中的几个相进行了数值分析。在分析中,除了正常的,单平面波LOFF,和色超导2SC/g2 SC相,我们还包括两个胶子相(胶子圆柱相II和胶子色自旋锁定相)。结果表明,这两个胶子相是动态实现的,并在此分析的基础上,在这种介质中的耦合强度的相图建议。特别是,它表明,胶子相是积极有利的参数空间的一个广泛的区域。另一方面,也存在LOFF相位稳定的窗口。2SC态和正常态分别在强耦合和弱耦合区域中实现,正如预期的那样。

英文摘要:

A numerical analysis of several phases in the cold neutral two flavor dense quark matter is realized. In the analysis, besides the normal, single plane wave LOFF, and color superconducting 2SC/g2SC phases, we also include two gluonic phases (the gluonic cylindrical phase II and the gluonic color-spin locked one). It is shown that these two gluonic phases are dynamically realized and, on the basis of this analysis, the phase diagram with respect to the coupling strength in this medium is suggested. In particular, it is shown that the gluonic phases are energetically favorable in a wide region of the parameter space. On the other hand, there also exists a window where the LOFF phase is stable. The 2SC state and the normal one are realized in the strong and weak coupling regimes, respectively, as was expected.
