Analog Schwarzschild-like geometry in fluids with external pressure

General Relativity and Quantum Cosmology 2022-04-06 v2 High Energy Physics - Theory

Abstract

We study acoustic geometry in fluids with external pressure. In particular, we examine the conditions under which the acoustic metric mimics a Schwarzschild-like metric. We demonstrate that it is possible to mimic a Schwarzschild-like geometry in a consistent way only in the framework of relativistic acoustic geometry.
