Importance of on-site interaction in graphene
Hari P. Dahal, Jean-Pierre Julien, A. V. Balatsky
We use the Gutzwiller method to investigate the importance of the on-site Coulomb interaction in graphene. We apply it to Hubbard Hamiltonian to study the renormalization of the ki…
Wigner crystallization in a single and bilayer graphene
Hari P. Dahal, Tim O. Wehling, Kevin S. Bedell +2
We study the possibility of Wigner crystallization in both single- and and bi-layer graphene using a real space tight binding model. In addition to verifying our earlier prediction…
Local impurity effects in superconducting graphene
T. O. Wehling, H. P. Dahal, A. I. Lichtenstein +1
We study the effect of impurities in superconducting graphene and discuss their influence on the local electronic properties. In particular, we consider the case of magnetic and no…
