Holographic Path to the Turbulent Side of Gravity
Physical Review X, 2014 We study the dynamics of a 2+1-dimensional relativistic viscous conformal fluid in Minkowski spacetime. Such fluid solutions arise as duals, under the “gravity/fluid correspondence,” to 3+1-dimensional asymptotically anti–de Sitter (AAdS) black-brane ...
