Abstract
Exact finite-lattice results for the optical conductivity of Hubbard models near half-filling are compared with recent experimental data for the dopant- and photoinduced mid-infrared absorption of cuprate high- materials. An as yet unobserved photoinduced absorption feature in the 4–6 eV range is predicted.
