In this paper we study the real-time evolution of heavy quarkonium in the quark-gluon plasma (QGP) on the basis of the open quantum systems approach. In particular, we shed light on how quantum dissipation affects the dynamics of the relative motion of the quarkonium state over time. To this end we present a novel nonequilibrium master equation for the relative motion of quarkonium in a medium, starting from Lindblad operators derived systematically from quantum field theory. In order to…

In the quark-gluon plasma, it is well known that the evolution of quarkonia is affected by the screening of the interaction between the quark and the antiquark. In addition, an exchange of energy and

TLDR
It is found that the real part of the complex valued static quark-antiquark potential lies close to the color singlet free energies in Coulomb gauge and shows Debye screening above the (pseudo)critical temperature T_{c}.
