| Abstract: | A doublon formalism ofd-p model Hubbard Hamiltonian is studied only with transfer integrals, and without the superexchange term. This gives excellent doping-dependent features ofT c in high-T c cuprates. |
| Keywords: | High-T c superconductor Hubbard model d-p model doping Cooper pair |
