要旨:
We consider the holographic hydrodynamics of black holes in generally
covariant gravity theories with a preferred time foliation. Gravitational
perturbations in these theories have spin two and spin zero helicity modes with
generically different speeds. The black hole solutions possess a spacelike
causal boundary called the universal horizon. We relate the flux of the spin
zero perturbation across the universal horizon to the new dissipative transport
in Lifshitz field theory hydrodynamics found in arXiv:1304.7481. We construct
in detail the hydrodynamics of one such black hole solution, and calculate the
ratio of the shear viscosity to the entropy density.
