Hydrodynamics of a black brane in Gauss–Bonnet massive gravity

M Sadeghi, S Parvizi - Classical and Quantum Gravity, 2016 - iopscience.iop.org
A black brane solution to Gauss–Bonnet massive gravity is introduced. In the context of
AdS/CFT correspondence, the viscosity to entropy ratio is found by the Green–Kubo formula …

Zero-viscosity limit in a holographic Gauss-Bonnet liquid

S Grozdanov, AO Starinets - Theoretical and Mathematical Physics, 2015 - Springer

holography-like correspondence between the descriptions of a generic quantum system in …

Moving quark in a viscous fluid

N Abbasi, A Davody - Journal of High Energy Physics, 2012 - Springer
To study the rate of energy and momentum loss of a heavy quark in QGP, specifically in the
hydrodynamic regime, we use fluid/gravity duality and construct a perturbative procedure to …

Hydrodynamics of arcsin AdS black brane
