TL;DR
This paper investigates the third-order nonlinear optical susceptibility of C60 molecules using free-electron and Coulomb interaction models, showing how local-field corrections can align theoretical results with experimental data.
Contribution
It compares free-electron and Coulomb interaction models for chi(3) in C60 and demonstrates the importance of local-field corrections for accurate predictions.
Findings
Free-electron model agrees with experimental chi(3) values.
Coulomb interactions reduce chi(3) by an order of magnitude.
Local-field corrections restore agreement with experiments.
Abstract
The third-order nonlinear optical susceptiblity chi(3) of a C60 molecule is calculated by using a free-electron model as well as by taking Coulomb interactions into account. The free-electron model yields chi(3) magnitudes which are in agreement with experiment. Althugh Coulomb interactions reduce chi(3) by one order of magnitude, local-field corrections can be invoked to recover the agreement.
