  In this paper, we investigate the dynamics of a heavy quark under the plasmas
correspond to three dimensional hairy black holes. We utilize the AdS/CFT
correspondence to study the holographic Brownian motion of this particle in
different kinds of hairy black holes. For uncharged black hole at low frequency
limit we derive analytic expressions for correlation functions and response
functions and verify that the fluctuation-dissipation theorem holds in the
presence of a scalar field in the metric background. In the case of charged
black hole, we think that the results are similar to what derived for uncharged
black hole.
