Critical Exponents of Modified GravityComments: 15 pages
In the context of modified gravity, we construct the two-point functions of scalar and tensor operators in the quantum field theory, in the presence of a potential, in the vicinity of a black hole with a radius closer to the black hole horizon. The results are used to determine the critical exponents of the modified gravity theory. Four of the exponents are found to be proportional to $1/c$, while the other two are not. This gives us a new method for computing the critical exponents of modified gravity, which is based on the result of the two-point functions. As an application, we calculate the critical exponents of modified gravity in the vicinity of two black holes with a radius close to the black hole horizon.
