The Energy Spectrum and the Optical Absorption Spectrum of C-36 Fullerene Within the Hubbard Model

摘要

Using the Hubbard model in an approximation of static fluctuations, analytical relations of anticommutator Green's functions and energy spectra of C-36 fullerene and La@C-36 endohedral fullerene with the D-6h symmetry groups are obtained. Using the group theory methods, a classification of the energy states is performed and the allowed transitions in the energy spectra of the C-36 and La@C-36 molecules are determined.
