| contents | We investigate the electrical conductivity of the quark-gluon plasma (QGP) using a non-perturbative resummation scheme incorporating the Gribov-modified gluon propagator. The electrical conductivity is evaluated by solving the relativistic Boltzmann transport equation within the relaxation-time approximation, where the relaxation times are obtained from microscopic two-body scattering amplitudes. A quasiparticle description is employed for quarks, providing a unified framework for studying transport properties across both weakly and strongly coupled regimes. Above the deconfinement transition temperature, we estimate the electrical conductivity of the QGP and compare our results with available lattice QCD data and various phenomenological models, finding good agreement with the lattice results. |
