摘要
论证了 U(1)×U(1)规范场论中对称性自发破缺的种种要求而导致的对超导弦势参数的一些限制条件。联系高温氧化物超导体的主要特征,研究了玻色场、费米场及其相互作用的耦合理论。并试图用上述结果定性讨论超导体的电流密度分布、磁场穿透深度变化和磁引斥力共存问题。
We demonstrate the constraint conditions of potential parameters whi-ch are required to break symmetry spontaneously ia an. U(1)×U(1) guage field theory .The coupled theories of besonic field, fermionic field and its interaction are studied associted with the main characteristic of high-temperature oxide superconductors. Using the results mentioned above we attempt to discuss the distribution of current density and the changes of magnetic filed penetration depth as well as the question that the magnetic attractive and repulsive forces are coexist in o-xide superconductors.
