高温超导层状势研究

本文对文献中提出的层状势作了较为深入的研究,作出了相互作用强度U与ω间关系的曲线,U与电子密度N_c~0间关系的曲线和U与铜氧层数l间的关系曲线。进而对层状势的微观机制——Cu-O层的有效哈密顿量进行了研究,得到了铜氧层的有效哈密顿量,讨论了空穴(附属费密子) 凝聚成库柏对的条件。

Study of Layer Potential for High-Temperature Superconductor

This articl makes a deep study on layer potential developed in reference[1]. The curves that de-scribe the relation between U and electron density N_e~0, and the relation between Cu-O plane number land U, are traced. Furthermore, this article studies the micromechanism of layer potential-effectiveHamiltonian for Cu-O layer. Effective Hamiltonian for Cu-O layer is obtained. The condition forholes (slave-fermions) to be condensed to Cooper pairs is dicussed.
