Collective acoustic modes in liquids: a comparison between the generalized-hydrodynamics and memory-function approaches

The most familiar approaches used to describe the dynamical structure factor from adiabatic density fluctuations in liquids are based on generalized hydrodynamics and on the memory function, respectively. We show that, contrary to the common belief, the two approaches are not fully equivalent. In pa...
