Abstract
The study of transport coefficients of strongly interacting matter gained impetus after the discovery of the best fluid ever created in ultrarelativistic heavy-ion collision experiments. In this article, we have calculated one such coefficient, viz., electrical conductivity of the quark gluon plasma (QGP) phase, which exhibits an anisotropy in the momentum space. The relativistic Boltzmann's kinetic equation has been solved in the relaxation-time approximation to obtain the electrical conductivity. We have used the quasiparticle description to define the basic properties of QGP through the distribution functions of partons. We have compared our results with the corresponding results obtained in lattice as well as other model calculations. Further, we extend our model to calculate the electrical conductivity at finite chemical potential.
