Indirect exchange of magnetic impurities in zigzag graphene ribbon
J. H. Sun, F. M. Hu, H. K. Tang +2
We use quantum Monte Carlo method to study the indirect coupling between two magnetic impurities on the zigzag edge of graphene ribbon, with respect to the chemical potential .…

Magnetic impurity in the vicinity of a vacancy in bilayer graphene
J. H. Sun, F. M. Hu, H. K. Tang +1
We use quantum Monte Carlo method to study a magnetic impurity located next to a vacancy in bilayer graphene with Bernal stacking. Due to the broken symmetry between two sublattice…

Magnetic Impurity in Bernal Stacked Bilayer Graphene
J. H. Sun, F. M. Hu, H. K. Tang +1
We investigate a magnetic impurity in Bernal stacked bilayer graphene by a non-perturbative numerical exact approach. In the two cases we study, impurity is placed on the top of tw…
