The Kondo insulating materials present a particularly simple limiting case of the strongly correlated electron lattice problem, one occupied f-state interacting with a single half-filled conduction band. Experiment shows that the solution to this problem has some remarkably simple aspects. Optical conductivity data display the strong coupling nature of this physics. © 1995.
