论文摘要
我们对量子染色体动力学（QCD）中可能的相图进行基础和教学评论。当前，重点是关键终点的出现，在该点终点，无序和有序的阶段相遇。但是，在许多模型中，也出现了一个Lifshitz点。在LIFSHITZ点，三个阶段相遇：无序，有序，一个在空间不均匀阶段出现的地方。在平均场理论的层面上，Lifshitz点的外观不会显着影响相图。但是，我们认为，关于Lifshitz点的波动在红外线中非常强，并显着改变了相图。我们详细讨论了与非疾病聚合物的类比，在该聚合物中，Lifshitz政权产生了双连续的微乳液。我们简要提及与QCD相图的可能相关性。
We give an elementary and pedagogical review of the phase diagrams which are possible in Quantum ChromoDynamics (QCD). Currently, the emphasis is upon the appearance of a critical endpoint, where disordered and ordered phases meet. In many models, though, a Lifshitz point also arises. At a Lifshitz point, three phases meet: disordered, ordered, and one where spatially inhomogeneous phases arise. At the level of mean field theory, the appearance of a Lifshitz point does not dramatically affect the phase diagram. We argue, however, that fluctuations about the Lifshitz point are very strong in the infrared, and significantly alter the phase diagram. We discuss at length the analogy to inhomogenous polymers, where the Lifshitz regime produces a bicontinuous microemulsion. We briefly mention the possible relevance to the phase diagram of QCD.
