We explore the existence of conformal field theories that persistently break a global symmetry at finite temperature. We identify vector models in (3-ε) spatial dimensions that have internal symmetries broken at any temperature. We study these systems in the small ε regime and in the large rank limit. The latter displays a conformal manifold and a moduli space of vacua deformed at finite temperature. We touch upon a candidate in d=2 dimensions.
我们探索了在有限温度下持续打破全局对称性的共形场论的存在性。我们确定了在（3 - ε）维空间中具有在任何温度下都被打破的内部对称性的矢量模型。我们在小ε区域和大秩极限下研究这些系统。后者展示了一个共形流形和在有限温度下变形的真空模空间。我们还提到了一个二维的候选模型。
