Observation of the Gap and Kinetic Energy in a Correlated Insulator
Abstract
Fundamental energies are determined optically for an ensemble of correlated electrons in an anti-ferromagnetic insulator, V_2O_3. The observed variation of the energy gap and the kinetic energy are compared quantitatively to some approximate solutions of the Hubbard Hamiltonian.
