  The chromo-electromagnetic field fluctuations in the quark-gluon plasma (QGP)
play an important role as these field fluctuations result energy gain of heavy
quarks. We consider these fluctuations and evaluate the transport coefficients,
e.g., drag and diffusion coefficients of charm quarks and shear viscosity to
entropy density ratio ($\eta/s$) of the QGP. We find a significant effect of
such fluctuations on the transport coefficients. These fluctuations cause a
reduction of the drag and diffusion coefficients. We also observe that the
shear viscosity to entropy density ratio of the QGP is closer to the value
obtained in Lattice QCD (LQCD) and functional renormalization group
calculations when the effects of such fluctuations are included.
