Abstract

The anticommutative Green’s functions were derived in an analytical form, and the energy spectra of С₂₆ fullerene and endohedral U@C₂₆ fullerene of symmetry group D_3h were obtained within the Hubbard model in the mean-field approximation. Using group theory methods, the classification of energy states was carried out, and the allowed transitions in the energy spectra of С₂₆ and U@C₂₆ molecules of symmetry group D_3h were determined.

哈伯德模型中富勒烯 C26 的能谱和光学特性

摘要

反交换格林函数以解析形式导出，并在平均场近似的哈伯德模型中获得С ₂₆富勒烯和对称群D _{3h 的}内嵌U@C ₂₆富勒烯的能谱。使用群论方法，进行了能态分类，并确定了对称群D _3h С ₂₆和U@C ₂₆分子能谱中允许的跃迁。
