Backreaction effects due to matter coupled higher derivative gravity
arXiv:1409.8019 · doi:10.1142/S0217732315500650
Abstract
AdS-hydrodynamics has proven to be a useful tool for obtaining transport coefficients observed in the collective flow of strongly coupled fluids like quark gluon plasma (QGP). Particularly, the ratio of shear viscosity to entropy density obtained from elliptic flow measurements can be matched with the computation done in the dual gravity theory. The experimentally observed temperature dependence of requires the study of scalar matter coupled AdS gravity including higher derivative curvature corrections. We obtain the backreaction to the metric for such a matter coupled AdS gravity in -dimensional spacetime due to the higher derivative curvature corrections. Then, we present the backreaction corrections to shear-viscosity and entropy density .
