Abstract: Potential between test particles is an established concept in the vacuum. In the medium, its extension is not unique. In this talk, I will explain one of such extensions using the real time propagator. I will focus on the imaginary part of the potential and its universal power law at long distances by showing three examples. Furthermore, I will also discuss most infrared behavior using hydrodynamic fluctuations.
