Kondo Quantum Criticality of Magnetic Adatoms in Graphene
2011
Physical Review Letters
We examine the exchange Hamiltonian for magnetic adatoms in graphene with localized inner shell states. On symmetry grounds, we predict the existence of a class of orbitals that lead to a distinct class of quantum critical points in graphene, where the Kondo temperature scales as T_K∝|J-J_c|^1/3 near the critical coupling J_c, and the local spin is effectively screened by a super-ohmic bath. For this class, the RKKY interaction decays spatially with a fast power law ∼1/R^7. Away from half
