Numerical Approach to Magnetic Mechanism of Superconductivity
Since the discovery of high-Tc superconductors, various models have been proposed and investigated torn different point of view to clarify the mechanism of high-Tc superconductivity. We start with a two-band d-p model with copper and oxygen orbitals in the CuO 2 plane of the high-Tc superconductors. The models investigated in the numerical analysis include the original two-band d-p model, the coupled spin-fermion model and the t-J model.
