We place the theory on a cylinder in a set of homogeneous, unstable initial states. The dual gravity configurations are black branes afflicted by a Gregory-Laflamme instability. We numerically evolve Einstein's equations to follow the instability until the system settles down to a stationary, inhomogeneous black brane. The dual gauge theory states have constant temperature but non-constant energy density. We show that the time evolution of the instability and the final states are accurately described by second-order hydrodynamics. In the static limit, the latter reduces to a single, second-order, non-linear differential equation from which the inhomogeneous final states can be derived.14 p.application/pdfengcc-by (c) Attems, Maximilian et al., 2017http://creativecommons.org/licenses/by/3.0/esForats negres (Astronomia)HolografiaHidrodinàmicaBlack holes (Astronomy)HolographyHydrodynamicsinfo:eu-repo/semantics/article6730082018-04-20info:eu-repo/semantics/openAccess
