The effect of higher derivative correction on $η/s$ and conductivities in STU model
higher derivative conductivities in STU model

In this paper we study the ratio of shear viscosity to entropy, electrical and thermal conductivities for the R-charged black hole in STU model. We generalize previous works to the case of a black hol...

Higher Derivative Quantum Gravity Four Dimensions
2010/10/18
We investigate the role of the Gauss-Bonnet term for the n = 4 and n = 4¡e renormalization group, for both conformal and general versions of the theory. The cancellation of the quantum effects o...
