- W2991453670 abstract "摘要 本文讨论两种典型的价涨落化合物——SmB6和SmS——的基态性质。由于Sm离子上的定域的直接d-f杂化被反演对称性禁戒,本文采用声子中介的定域的非直接d-f杂化模型。采用正则变换方法处理声子中介的d-f杂化项,得到一个“小极化子”类型的有效哈密顿量。应用自洽场近似处理这个有效哈密顿量,得出基态时的非零能隙和f能级的非整数占有数。这些结果可用以解释在SmB6和SmS中观察到的小能隙和价涨落现象。 Abstract The ground state properties of the Sm-based valence fluctuation compounds are discussed by introducing an indirect on-site hybridization mediated by phonons, as the direct on-site hybridization is forbidden by inversion symmetry. The Hamihonian including this indirect hybridization is transformed into an effective Hamihonian of a small polaron type by means of a. canonical transformation. A self-consistent field approximation is used, a non-zero energy gap and the noninteger occupation of the f level have been given. The results obtained can be used to explain the small energy gap and the valence fluctuation phenomena observed in SmB6 and SmS. 作者及机构信息 郑杭 1. 上海交通大学应用物理系 Authors and contacts ZHENG HANG 1. 上海交通大学应用物理系 参考文献 施引文献" @default.
