Title
Cool dense QCD and in-homogeneous phases (a.k.a. chiral spirals)
Speaker
Dr. Semeon Valgushev (National Tsing Hua University)Abstract
We discuss dense cool QCD where a region with spatially inhomogeneous condensate might emerge. In that case, QCD phase diagram may exhibit a Lifshitz regime, which can appear either instead of, or in addition to Critical End Point. We study the Lifshitz regime using a combination of large-N expansion and numerical lattice simulations of an effective O(N) sigma model. We find evidence that quantum fluctuations disorder inhomogeneous condensate (”chiral spirals”) and give rise to unusual quantum spin-liquid phase. We also discuss how this novel phase can be detected experimentally.
