Irrespective of the differences in microscopic\r\nproperties, we find a remarkable degree of universality in the response\r\nfunctions from conformal theories. We find that the response to scalar\r\nperturbations in kinetic theory can be effectively described by a pair of one\r\nhydrodynamic sound mode and one non-hydrodynamic mode. We find that even beyond\r\nthe range of validity of hydrodynamics, the energy-momentum response in\r\nposition space can be effectively described by one single mode with non-trivial\r\ndispersion relation and residue.","lang":"eng"}],"publication":"arXiv:2306.09094"}
