Description
Hydrodynamics can describe the thermalized quark-gluon plasma phase of heavy-ion collisions. Extending its validity to pre-equilibrium stages requires accounting for short-lived non-hydrodynamic modes. In this talk, I present a method that retains selected information from these modes to extend the validity of hydrodynamics beyond the conventional hydrodynamic regime. I apply this method to both weakly coupled kinetic theory and strongly coupled holography. In both cases, the nearest-neighbour coupling structure allows higher non-hydrodynamic degrees of freedom to be propagated iteratively into the hydrodynamic mode, extending its regime of validity. This provides a common framework for comparing collective dynamics across microscopically distinct theories.
