We present analytical expressions for the current-current correlation function in graphene for arbitrary frequency, wave vector, doping, and band gap induced by a mass term. In the static limit, we analyze the Landau (orbital) and Pauli magnetization, as well as the Lindhard correction, which describes Friedel and Ruderman-Kittel-Kasuya-Yosida oscillations. In the nonrelativistic limit, we ...
