Heavy fermion systems

The single-orbital Anderson impurity model using graphene as the host material is considered for the case where the impurity is placed on top of a carbon atom of the graphene lattice. This is an excellent setup for the r = 1 pseudogap impurity model, where there exists a quantum phase transition from the free local moment phase to the Kondo screening phase.
