Graphene, Silicene, $\mathrm{MoS}_2$ and other similar two-dimensionalstructures have unusual electronic properties that lend themselves to exoticdevice applications. These properties emanate from the fact that the electronsare endowed with Dirac fermion-like attributes. Thus these materials are notonly characterized by certain fundamental principles, they also have amazingpractical uses. Our emphasis here is on one such basic property concerningnonlinear response to time-dependent electric fields. We set up a firstprinciple quantum master equation for the underlying density operator which isbased on microscopic interactions between the Dirac electron with phonons andother electrons. While such an equation has general applicability to a varietyof non-equilibrium phenomena in two-band systems, we focus onto the case ofnonlinear optical conductivity. The derived results are separately analyzed forgraphene, silicene and $\mathrm{MoS}_2$, and comparison made with other knownresults.
