We consider a nonlinear Schroedinger equation in two spatial dimensionssubject to a periodic honeycomb lattice potential. Using a multi-scaleexpansion together with rigorous error estimates, we derive an effective modelof nonlinear Dirac type. The latter describes the propagation of slowlymodulated, weakly nonlinear waves spectrally localized near a Dirac point.
