Optical Properties of a Correlated Electron System: V_2O_3

Abstract

The optical spectrum of V_2O_3 is found to resemble a Hubbard model system as described in an infinite-dimensional approximation. Assuming the validity of this comparison, we parameterize the effective Coulomb repulsive energy, the bandwith, and the mass enhancement. We suggest implicitly that these results should be compared with the cuprate and heavy Fermion superconductors.
