超导的光子云机制
摘要
自从发现超导体的特性后,出现了多种超导理论,常规超导体的BCS理论,非常规超导体的理论如激子模型、自旋涨落模型、Luttinger液体理论、自旋配对理论等,这些理论在某些方面取得了成功,但成熟的超导体理论至今还没有出现,说明超导体的理论研究仍然处于百家争鸣阶段,探索新的超导电子对机制仍有积极的理论价值。
本文根据超导体特性的产生来源于电磁作用这个实验事实,认为光子与电子之间的间接相互作用(交换光子)构成电子对,探讨了电子对的光子云机制,计算了基态能隙及其与临界温度的关系、Hg的临界温度,讨论超导的同位素效应、超导的压强效应等,得到了一些与实验结果比较吻合的结论。但本文的光子云电子对机制仍需要进一步的探索。
Many superconductivity theories have been developed after the discovery of the superconductivity. For example, BCS theory of the conventional superconductors, exciton model and Luttinger’s liquid theory of unconventional superconductors etc. These theories are successful in some aspects. But the theory of some unconventional superconductivity has not still been established. The key to the building of the lately superconductivity theory is look for the formation mechanism of electronic pairs.
According to the experimental results that superconducting properties arise from the electromagnetic action, we regard photon and electric charge as the superconducting elements. In this thesis, we present an electronic pairs information mechanism which comes from exchanged virtual photons between a pair of electrons, we have discussed the critical temperature and the isotope effect of Hg, the pressure effect of superconductor. Agreements are obtained by comparing theoretical results with experiments. However, it is only attempt to study superconductivity and necessary to make further investigation.
