研究了大质量引力子对全息热化过程的影响。在此之前，我们首先通过直接求解引力方程，求出de Rham-Gabadadze-Tolley（dRGT）质量引力中的广义Vaidya-AdS解。然后，利用Misner-Sharp能量和统一第一定律研究了这些Vaidya-AdS解的热力学性质，也表明了大质量引力处于热力学平衡状态.此外，我们还采用等时两点关联函数探讨了对偶场论中的热化过程，并从AdS/CFT对应的角度考察了引力子质量参数对热化过程的影响.结果表明，引力子质量参数将增加全息热化过程。
We investigate the effect of massive graviton on the holographic thermalization process. Before doing this, we first find out the generalized Vaidya-AdS solutions in the de Rham–Gabadadze–Tolley (dRGT) massive gravity by directly solving the gravitational equations. Then, we study the thermodynamics of these Vaidya-AdS solutions by using the Misner–Sharp energy and unified first law, which also shows that the massive gravity is in a thermodynamic equilibrium state. Moreover, we adopt the two-point correlation function at equal time to explore the thermalization process in the dual field theory, and to see how the graviton mass parameter affects this process from the viewpoint of AdS/CFT correspondence. Our results show that the graviton mass parameter will increase the holographic thermalization process.
