高温超导电性机制研究

Study on Mechanism for High--Temperature Superconductivity

本文从场论的角度探讨了强关联费米系统高温超导电性的机制。用SU(2)×U(1)规范场论对超导体系进行理论分析,并结合唯象描述以了解高温超导机制,对氧化物超导体临介温度的理论预言与实验数据相吻合。

An exploration of the mechanism for high-temperature superconductivityin strongly correlated Fermi systems, is given on the basis of the fieldtheory. By use of the SU(2)×U(1) gauge field theory, the theoreticalanalysis combined with phenomenological description for the systemsis made in the understanding of the mechanisms of high-temperaturesuperconductivity. Critical temperatures for oxide superconductorspredicted by the theory are consistent with experimental data.
