Holographic Superconductors in f(R) Gravity    [PDF]

Zhao Xue, Sheng-Liang Cui
We study the holographic superconductors in f(R) gravity, and show how the critical temperature and the condensate of the dual operator depend on the modifications to Einstein gravity. We first consider the black holes with constant curvature, which are clear in f(R) gravity. With the help of the matching method, the dependencies are carried out explicitly. Then we consider a planar black hole solution for a specific f(R) without imposing the constant curvature, which is asymptotic AdS spacetime. The corrections to the thermal dynamics of the black holes, the critical temperature and the condensates are all obtained in a perturbative approach. Some comments are given on the affections of the f(R) gravity to the holographic superconductors.
