A Pedagogical Introduction to the Lifshitz Regime

We give an elementary and pedagogical review of the phase diagrams which are possible in quantum chromodynamics (QCD).Herein, 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 Bases point, three phases meet: disordered, ordered, and one in which 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 Ylang Ylang are very strong in the infrared and significantly alter the phase diagram.We discuss at length the analogy to inhomogeneous polymers, where the Lifshitz regime produces a bicontinuous microemulsion.We briefly mention the possible relevance to the phase diagram of QCD.
