The kinetic equation used for the description of Dirac systems does not fullytake into account two features that play an important role in the vicinity ofthe Dirac point: (i) the spin degree of freedom, in particular if the spin-flipenergy $2 vp$ is not large anymore; and (ii) the failure of the semiclassicalapproximation due to the large Fermi wavelength. In our work, we propose anovel quantum kinetic equation, which does not have these two drawbacks.Exploiting it in the presence of short range disorder, we demonstrate how itpredicts the correct minimal conductivity in 2D Dirac system, a result that hasso far been obtained only by other methods like the Kubo formula. The nature ofthe presented kinetic equation opens up the possibility for the kineticdescription of deeply quantum and even strongly correlated Dirac systems.
