  The quark-gluon plasma, which is produced at an early stage of
ultrarelativistic heavy-ion collisions, is expected to be initially strongly
populated with chromodynamic fields. We address the question how heavy quarks
interact with such a turbulent plasma in comparison with an equilibrated one of
the same energy density. For this purpose we derive a Fokker-Planck transport
equation of heavy quarks embedded in a plasma of light quarks and gluons. We
first discuss the equilibrium plasma and then the turbulent one applying the
same approach, where the heavy quarks interact not with the plasma constituents
but rather with the long wavelength classical fields. We first consider the
three schematic models of isotropic trubulent plasma and then the simplified
model of glasma with the chromodynamic fields only along the beam direction.
The momentum broadening and collisional energy loss of a test heavy quark are
computed and compared to those of equilibrium plasma of the same energy
density.
