  Heavy quark transport coefficients in a strongly coupled Quark-Gluon Plasma
can be evaluated using a gauge/string duality and lattice QCD. Via this
duality, one can argue that for low momenta the drag coefficient for heavy
quarks is proportional to the spatial string tension. Such a tension is well
studied on the lattice that allows one to straightforwardly make
non-perturbative estimates of the heavy quark diffusion coefficients near the
critical point. The obtained results are consistent with those in the
literature.
