A model of clustered binary medium is proposed. It describes the anomalous behavior
of the linear (Lorentz—Lorentz function) and the nonlinear (nonlinear refractive
index) optical properties of supercritical CO2. Using computer simulation based on
the molecular dynamics, we verified the validity of this model, that describes the
anomalous behavior of the nonlinear refractive index of supercritical CO2 in the
vicinity of the Widom line, due to clustering.
