Horava-Lifshitz Black Hole Hydrodynamics

Understand

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.
