有多少相在手性临界点相遇?

How many phases meet at the chiral critical point?

Dominik Nickel

摘要:

我们探讨了NJL型模型的相图附近的手征临界点允许与空间不均匀的手征凝聚相。在手征极限中,平均场相图中那些相在能量上是优选的区域一般都到达手征临界点。在这附近的优选的非均匀基态可能类似于畴壁孤子的晶格。这就提出了它们与QCD相图的相关性问题。

英文摘要:

We explore the phase diagram of NJL-type models near the chiral critical point allowing for phases with spatially inhomogeneous chiral condensates. In the chiral limit it turns out that the region in the mean-field phase diagram where those phases are energetically preferred very generically reaches out to the chiral critical point. The preferred inhomogeneous ground state in this vicinity possibly resembles a lattice of domain wall solitons. This raises the question of their relevance for the phase diagram of QCD.
