Jia Liu, Qiang Han, L. B. Shao, Z. D. Wang

摘要:

在Richardson模型的框架下,精确求解了一类具有自旋轨道相互作用或塞曼耦合的电子对模型。基于自旋-轨道相互作用情形的精确解,严格地证明了对序参量总是具有$p+ip$波对称性,而与对相互作用的强度无关,从而证明了平均场论的一个重要结论.分别对两个具有自旋轨道相互作用和塞曼耦合的简单系统进行了分析。

英文摘要:

A type of electron pairing model with spin-orbit interactions or Zeeman coupling is solved exactly in the framework of Richardson ansatz. Based on the exact solutions for the case with spin-orbit interactions, it is shown rigorously that the pairing order parameter has always the $p+ip$-wave symmetry regardless of the strength of pairing interaction, justifying an important conclusion obtained by the mean field theory. Analytical results are derived for two simple systems with respectively spin-orbit interactions and Zeeman coupling.
