The static and dynamic structure of liquid Al is studied using the orbital free ab initio molecular dynamics
method. Two thermodynamic states along the coexistence line are considered, namely T=943 and 1323 K, for
which x-ray and neutron scattering data are available. A kinetic-energy functional which fulfills a number of
physically relevant conditions is employed, along with a local first-principles pseudopotential. In addition to a
comparison with experiment, we also compare our ab initio results with those obtained from conventional
molecular-dynamics simulations using effective interionic pair potentials derived from second-order pseudopotential
perturbation theory.
