Abstract
Based entirely on the cuprate structure, a microscopic theory for high-temperature superconductivity is proposed. This theory produces quantitative fits to the normal phase properties such as Hall effect, resistivity, thermoelectric power, etc. It also reveals the existence of a pseudo-gap structure that has nodes along the diagonals of the basal plane. In the superconducting phase, an inverse parabolic dependences of T c on hole density is a natural consequence. The optimum T c value derived from the corresponding intrinsic hole density obtained from electronic structure agrees with the value obtained experimentally. This theory can also explain the observation of a strong spin fluctuation near T c in the YBa 2Cu 3O 7 (YBCO) and the absence of such in the Bi 2Sr 2CaCu 2O 8 (BiSCCO) system.
