Dynamical horizon entropy and equilibrium thermodynamics of generalized gravity theories
Shao-Feng Wu, Xian-Hui Ge, Peng-Ming Zhang +1
We study the relation between the thermodynamics and field equations of generalized gravity theories on the dynamical trapping horizon with sphere symmetry. We assume the entropy o…
Deriving the gravitational field equation and horizon entropy for arbitrary diffeomorphism-invariant gravity from spacetime solid
Shao-Feng Wu, Bin Wang, Xian-Hui Ge +1
Motivated by the analogy between the spacetime and the solid with inhomogeneous elasticity modulus, we present an alternative method to obtain the field equation of any diffeomorph…
Shear viscosity and instability from third order Lovelock gravity
Xian-Hui Ge, Sang-Jin Sin, Shao-Feng Wu +1
We calculate the ratio of shear viscosity to entropy density for charged black branes in third order Lovelock theory. For chargeless black branes, the result turns out to be consis…
Shear viscosity, instability and the upper bound of the Gauss-Bonnet coupling constant
Xian-Hui Ge, Sang-Jin Sin
We compute the dimensionality dependence of for charged black branes with Gauss-Bonnet correction. We find that both causality and stability constrain the value of Gauss-Bonn…
