Extended Recursion in Operator Space (EROS), a new impurity solver for the single impurity Anderson model
Jean-Pierre Julien, R. C. Albers
We have developed a new efficient and accurate impurity solver for the single impurity Anderson model (SIAM), which is based on a non-perturbative recursion technique in a space of…

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…
