Analog Dual To A 2+1-Dimensional Holographic Superconductor

We study an analog hydrodynamic model that mimics a 3 + 1 AdS planar BH spacetime dual to a 2 + 1-dimensional superconductor. We demonstrate that the AdS(4) bulk and its holographic dual could be realized in nature in an analog gravity model based on fluid dynamics. In particular we mimic the metric of an O (2) holographic superconductor and calculate the entanglement entropy of a conveniently designed subsystem at the boundary of the analog AdS(4) bulk.
