From a purely quantum field theoretic standpoint finding the non-hydrodynamic, non-relativistic
behavior of strongly coupled fluids is difficult since couplings run at lower energies. With the advent
of the AdS/CFT correspondence, one may find the hydrodynamic and non-hydrodynamic behavior of
such fluids in the non-relativistic regimes (including the relativistic regime). In my talk we will introduce
non-relativistic holography (with the weak form of the non-relativistic version of the AdS/CFT correspondence),
walk through the calculation of the fluid’s quasinormal modes, and present distinct differences of behaviors
between the non-relativistic and analogous relativistic fluid. Several key differences are due to the presence
of the khronon field, introducing new degrees of freedom and allowing for arbitrarily speed of propagation
of gravitons, allowing for gravitons of different spin to propagate at different speeds.
