Phase diagram of Yang-Mills theories in the presence of a theta term
摘要：
研究了非阿贝尔纯规范理论在拓扑θ项存在下的相图。解禁闭温度对θ的依赖关系是由解析延拓和重新加权确定的，得到了一致的结果。图的一般结构进行了讨论的基础上，大N的考虑和可能的类比和对偶的QCD的相图中存在的一个假想的重子化学势。
英文摘要：
We study the phase diagram of non-Abelian pure gauge theories in the presence of a topological theta term. The dependence of the deconfinement temperature on theta is determined on the lattice both by analytic continuation and by reweighting, obtaining consistent results. The general structure of the diagram is discussed on the basis of large-N considerations and of the possible analogies and dualities existing with the phase diagram of QCD in presence of an imaginary baryon chemical potential.
