Unconventional superconductivity and charge ordering in an extended ionic Hubbard model on the triangular lattice
To address the issues of superconducting and charge properties in hydrated sodium cobalt, we investigate an extended ionic Hubbard model on the triangular lattice, which includes off-site attractions between sites with minor charges. Our quantum Monte Carlo simulations show that close to quarter fil...
