  In presence of the non-ideal plasma effects, Heavy Quarks (HQs) carry out non
linear random walk inside Quark-Gluon Plasma (QGP) and in the small momentum
transfer limit, the evolution of the HQ distribution is dictated by the Non
Linear Fokker-Planck Equation (NLFPE). Using the NLFPE, we calculate the
transport coefficients (drag and diffusion) of heavy quarks travelling through
QGP. We observe substantial modification in the momentum and temperature
variation of the transport coefficients; and this will modify the physical
picture we are having about the transport of heavy quarks inside QGP, and
hence, about the characterisation of the plasma.
