| Summary: | Increasing attention has been paid in recent years to the problem of electron interactions in solids because of their significant effects on various physical properties of solids, as for example the transport properties and the electronic specific heat. The problem has been idealized to an interacting electron gas imbedded in a uniform background of positive charge, the lattice of positive ions. The whole system is then neutral. For most metals this is fairly representative of the actual situation. As early as 1934, Wigner suggested the importance of the "correlation energy", a term introduced by him.
