Title:
Hydrodynamics of Spinning Holographic Fluids

Abstract:
We  find  hydrodynamic  behavior  in  large  simply  spinning  five-dimensional Anti-de Sitter black holes. These are dual to spinning quantum fluids through the AdS/CFT correspondence constructed from string theory. Due to the spatial anisotropy introduced by the angular momentum, hydrodynamic transport coefficients are split into groups longitudinal or transverse to the angular momentum, and aligned or anti-aligned with it.  Analytic Expressions are provided for the two shear viscosities, the longitudinal momentum diffusion coefficient, two speeds of sound, and two sound attenuation coefficients.  Known relations between these coefficients are generalized to include dependence on angular momentum.The shear viscosity to entropy density ratio varies between zero and 1/(4π) depending on the direction of the shear.  These results can be applied to heavy ion collisions, in which themost vortical fluid was reported recently.  In passing, we show that large simply spinning five-dimensional Myers-Perry black holes are perturbatively stable for all angular momenta below extremality.
