| 摘要: |
| 相变和临界现象是热力学和统计力学中非常有趣的课题.引力与热力学有着深刻和本质的联系.接近临界点，涨落非常明显.因此，对于普通物质（由非引力作用控制的系统）在临界点附近如果我们忽略涨落，临界现象会变的非常不同.发现RN-AdS空间的临界指数在考虑到完全的量子微扰效应后保持不变.这个研究指出了引力系统与普通热力学系统的一个关键不同点. |

| Abstract: |
| Phase transition and critical phenomenon is a very interesting topic in thermodynamics and statistical mechanics. Gravity is believed to have deep and inherent relation to thermodynamics. Near the critical point,the perturbation becomes significant. Thus for ordinary matter (governed by interactions besides gravity) the critical behavior will become very different if we ignore the perturbations around the critical point,such as mean field theory. We find that the critical exponents for RN-AdS spacetime keep the same values even when we consider the full quantum perturbations. This indicates a key difference between gravity and ordinary thermodynamic system. |
