Abstract
We present further progress in a systematic approach to the microscopic understanding of the dynamics of strongly interacting quantum fluids. Employing the concept of dynamic multiparticle fluctuations, we derive equations of motion for fluctuating n-body densities. We apply the theory to calculate the dynamic structure function of liquid He4 as a function of density and find, without any phenomenological input, overall excellent agreement with both experiments and, as far as available, simulation data.
