Multiorbital Effects on Antiferromagnetism in Fe Pnictides
Katsunori Kubo, Peter Thalmeier
We apply a Hartree-Fock approximation to a two-orbital model proposed for Fe pnictide superconductors. It is found that the antiferromagnetic (AFM) order with the ordering vector Q…

Variational Monte Carlo study of ferromagnetism in the two-orbital Hubbard model on a square lattice
Katsunori Kubo
To understand effects of orbital degeneracy on magnetism, in particular effects of Hund's rule coupling, we study the two-orbital Hubbard model on a square lattice by a variational…
