de Rham-Gabadadze-Tolley质量引力中的Vaidya解及其推广

Vaidya solution and its generalization in de Rham-Gabadadze-Tolley massive gravity

Ping Li, Xin-zhou Li, Xiang-hua Zhai

摘要:

我们提出了一个详细的研究Vaidya解决方案及其推广的de Rham-Gabadadze-Tolley(dRGT)理论。由于引入Stückelberg场$ϕ^a$后,可以恢复其同态不变性,因此在有质量引力中增加了一个新的不变量$I^{ab}=g^{μν}\partial_μϕ^a\partial_νϕ^b$,这是对广义相对论中常遇到的不变量的补充.如果我们选择么正规范,就不存在传统的Vaidya解.本文得到了三种具有非幺正规范的自洽解,并相应地求出了Vaidya解、广义Vaidya解和Furry Vaidya解。作为副产品,我们得到了一系列毛茸茸的黑洞。Vaidya解及其在dRGT大质量引力中的推广描述了具有可变视界的黑洞。

英文摘要:

We present a detailed study of the Vaidya solution and its generalization in de Rham-Gabadadze-Tolley (dRGT) theory. Since the diffeomorphism invariance can be restored with the Stückelberg fields $ϕ^a$ introduced, there is a new invariant $I^{ab}=g^{μν}\partial_μϕ^a\partial_νϕ^b$ in the massive gravity, which adds to the ones usually encountered in general relativity. There is no conventional Vaidya solution if we choose unitary gauge. In this paper, we obtain three types of self-consistent ansatz with some nonunitary gauge, and find accordingly the Vaidya, generalized Vaidya and furry Vaidya solution. As by-products, we obtain a series of furry black hole. The Vaidya solution and its generalization in dRGT massive gravity describe the black holes with a variable horizon.
