Abstract

Using holography we have studied the evolution of Wilson loop of a quark-antiquark pair in a
dynamical strongly coupled plasma. The time-dependent plasma, whose dynamics is originated from
the energy injection, is dual to AdS-Vaidya background. The quark-antiquark pair is represented
by the endpoints of a string stretched from the boundary to the bulk. The evolution of the system
is studied by evaluating the expectation value of the Wilson loop, throughout the process. Our
results show that the evolution of Wilson loop depends on the speed of injecting energy as well as
the nal temperature of the plasma. For high enough temperatures and rapid energy injection, it
starts oscillating around its equilibrium value, immediately after the injection.
