Description
We report recent progress in extending relativistic hydrodynamics that is largely inspired by the gauge/gravity duality. First, we present a simple but nontrivial extension of Muller-Israel-Stewart (MIS) theory, namely MIS*, and demonstrate that it describes non-hydrodynamic response for both kinetic theory and strongly coupled super-Yang Mills theory. Second, we construct an effective field theory describing holography liquid with one conserved U(1) charge. In addition, such a theory includes K number of hidden local symmetries that are broken spontaneously. If K goes to the infinity limit, it reproduces the quasi-normal spectrum from holography.
