Monte Carlo-maximum entropy calculations of the conductivity of the infinite-dimensional periodic Anderson model are presented. We show that the optical conductivity displays anomalies associated with the exhaustion of conduction-band states near the Fermi energy including a Drude weight, which rises with temperature, with weight transferred from a temperature and doping-dependent mid-infrared (IR) peak and a low-frequency incoherent contribution. Both the Drude and mid-IR peaks persist up to very high temperatures. The resistivity displays a nonuniversal peak and two other regions associated with impuritylike physics at high temperatures and Fermi-Liquid formation at low T. [S0163-1829(99)04839-0].
