利用AdS/CFT方法研究了有限温度下的胶子凝聚（GC）。我们首先证明了在有规则视界的情况下，高温下GC是被禁的。然后我们考虑了引力反作用对胶子耦合的影响，证明了引力反作用产生奇异性，胶子凝聚的非零值是允许的。我们还研究了热力学量和痕量异常的存在下的GC。我们讨论了如何定义的温度存在的奇异性，禁止霍金温度。最后，我们描述了胶子凝聚的热力学，包括霍金-佩奇跃迁的影响。
We consider gluon condensation (GC) at finite temperature using AdS/CFT. We first show that in the presence of regular horizon, the GC is forbidden in high temperature. Then we consider gravity back-reaction to dilaton coupling and show that the back-reaction develops an singularity, and non-vanishing value of gluon condensation is allowed. We also study thermodynamic quantities and the trace anomaly in the presence of the GC. We discuss how to define a temperature in the presence of the singularity which forbids Hawking temperature. Finally we describe the thermodynamics of the gluon condensation including the effect of the Hawking-Page transition.
