Superconducting and correlated phases of an effective Hubbard model on the BCC lattice
Theja N. De Silva
We investigate the electronic phases of an effective Hubbard model on the body-centered-cubic lattice, motivated by alkali-doped fulleride molecular solids. The model incorporates…

Pathology of Schwinger boson mean field theory for Heisenberg spin models
Theja N. De Silva, Michael Ma, Fu Chun Zhang
We have re-analyze the Schwinger boson mean field theory (SBMFT) for Heisenberg spin models on the cubic lattice. We find that the second order phase transition point for magnetic…
