Abstract

A new Sesame-type table for the electrical conductivity of aluminum is described. The table is based on density functional theory calculations and ranges from 0.001 to 1 times solid density (2.7 g/cm^3 ), and from 0.01 to 1000 eV in temperature. The table is compared to other simulations and to experiments and is generally in good agreement. The high temperature, classical limit of the conductivity is recovered for the highest temperatures and lowest densities. The table is critically evaluated and directions for improvements are discussed.
