Description
As an effective field theory, relativistic hydrodynamics is fixed by symmetries up to a set of transport coefficients. In this talk, I will explain how microscopic causality leads to the existence of the hydrohedron: a universal convex geometry in the space of transport coefficients that contains every consistent theory of relativistic transport. I will analytically construct cross-sections of the hydrohedron corresponding to bounds on transport coefficients that appear in sound and diffusion modes for theories without stochastic fluctuations, including all large N holographic QFTs.
