The dilaton vacuum expectation value is set by a potential localized on a flat brane. We chart the elementary properties of these backgrounds for any admissible ν, and determine stability conditions of the brane-dilaton system. We find that the spectrum of metric fluctuations can be either continuous or discrete. It features a massless graviton mode confined between the brane and the curvature singularity, and a massive radion mode tied to brane-dilaton stability. We show that, in the presence of a bulk black hole, the holographic theory living on the brane features a perfect fluid. The equation of state of the holographic fluid interpolates between radiation, pressureless matter and vacuum energy as a function of ν. This extends earlier findings on holographic fluids. Our results suggest that the thermodynamics of the fluid mirrors precisely the thermodynamics of the bulk black hole.}, organization = {Project PID2020-114767GB-I00 and by the Ramón y Cajal Program under Grant RYC-2016-20678 funded by MCIN/AEI/10.13039/501100011033 and by “FSE Investing in your future”}, organization = {Junta de Andalucía under Grant FQM-225}, organization = {“Prórrogas de Contratos Ramón y Cajal” Program of the University of Granada}, organization = {Spanish MICIN under Grant PID2020-115845GB-I00}, organization = {Catalan Government under Grant 2021SGR00649}, organization = {CERCA program of the Generalitat de Catalunya}, publisher = {SpringerLink}, keywords = {Black Holes}, keywords = {Effective Field Theories}, keywords = {Gauge-Gravity Correspondence}, title = {Holographic fluids from 5D dilaton gravity}, doi = {10.1007/JHEP08(2024)077}, author = {Fichet, Sylvain and Megías Fernández, Eugenio and Quirós, Mariano}, }
