We examine the subband energy spectrum of a coupled symmetric Graphene double-quantum- dot system subject to Landau quantization in a normal magnetic eld. To formulate the dispersion relation, we construct the coupled double-dot Graphene Green`s function incorporating the eects of the magnetic eld, including both the Peierls phase factor as well as Landau quantization. The frequency poles of this Green`s function dene the Landau-quantized energy spectrum of the coupled Graphene double-dot system, and these subband energy states are explored here.
