Abstract

The calculation of dynamic properties of physical systems requiresthe knowledge of their total energy as a function of theirconfiguration. In this paper we review some techniques for makingthis evaluation feasible in liquid systems, in particular liquidmetals, through the use of pseudopotentials, and we also discuss howto construct the pseudopotentials in order to optimize their usewithin approximate theories for the total energy. Some results aregiven for pure metals and alloys.
