Behavior of a Magnetic Impurity in Graphene in the Presence of a Vacancy
F. M. Hu, J. E. Gubernatis, Hai-Qing Lin +2
With quantum Monte Carlo methods, we investigate the consequences of placing a magnetic adatom adjacent to a vacancy in a graphene sheet. We find that instead of the adatom propert…
Pairing in graphene: A quantum Monte Carlo study
Tianxing Ma, Zhongbing Huang, Feiming Hu +1
To address the issue of electron correlation driven superconductivity in graphene, we perform a systematic quantum Monte Carlo study of the pairing correlation in the t-U-V Hubbard…
Magnetic Impurities in Graphene
F. M. Hu, Tianxing Ma, Hai-Qing Lin +1
We used a quantum Monte Carlo method to study the magnetic impurity adatoms on graphene. We found that by tuning the chemical potential we could switch the values of the impurity's…
