Back reaction effects on the dynamics of heavy probes in heavy quark cloud

We holographically study the effect of back reaction on the hydrodynamical properties of $$ mathcal{n}=4 $$ strongly coupled super yang-mills (sym) thermal plasma. the back reaction we consider arises from the presence of static heavy quarks uniformly distributed over $$ mathcal{n}=4 $$ sym plasma. in order to study the hydrodynamical properties, we use heavy quark as well as heavy quark-antiquark bound state as probes and compute the jet quenching parameter, screening length and binding energy. we also consider the rotational dynamics of heavy probe quark in the back-reacted plasma and analyse associated energy loss. we observe that the presence of back reaction enhances the energy-loss in the thermal plasma. finally, we show that there is no effect of angular drag on the rotational motion of quark-antiquark bound state probing the back reacted thermal plasma.
