The Energy Spectrum and Optical Properties of Fullerene С36 within the Hubbard Model

详细

The anticommutator Green’s functions and the energy spectra of fullerene С₃₆ and endohedral fullerene La@C₃₆, with both of them belonging to the D_6h symmetry group, are obtained analytically within the Hubbard model in the mean-field approximation. Using group-theory methods, their energy states are classified and allowed transitions in the energy spectra of the С₃₆ and La@C₃₆ molecules, both belonging to the D_6h symmetry group, are determined.
