Symmetry in Nonlinear Mathematical Physics  2009
Oleksiy Kapitanchuk (Bogolyubov Institute for Theoretical Physics of NASU, Kyiv, Ukraine) Application of icosahedral symmetry to the study of electronic and optical properties of C_{60} fullerene Abstract:
We report on the symmetry aspects of our quantummechanical study of static t_{1u} ÄH_{g} JahnTeller problem in C_{60} anions and low energy monoexcitation spectra of C_{60} fullerene. The symmetry adapted configuration interaction method is used to define the multielectronic wave functions and to reduce the complicated calculations of the matrix elements. The role of electron correlation effects in the modeling of fullerene properties and appropriate shape of electronelectron interaction potential are discussed.
