Physical Review B - Condensed Matter and Materials Physics, 91-12. doi:10.1103/PhysRevB.91.125403 | Abstract: | We study the interaction between two magnetic adatom impurities in graphene using the Anderson model. The two-impurity Anderson Hamiltonian is solved numerically by using the quantum Monte Carlo technique. We find that the interimpurity spin susceptibility is strongly enhanced at low temperatures, significantly diverging from the well-known Ruderman-Kittel-Kasuya-Yoshida result which decays as R-3. | URI: | https://doi.org/10.1103/PhysRevB.91.125403 http://hdl.handle.net/11147/5958 |
