Dedicated to Professor Dr. Roland Zimmermann on the occasion of his 60th birthday Two basic methods to assess correlation effects on an ab initio level for excited states in semiconductors and insulators are presented. The construction of an effective Hamiltonian and a Green's function approach are
Further evidence is shown that a kinetic energy functional can be used as an exchange energy functional and, conversely, exchange used as a kinetic energy functional, with a proper transformation of energy as a functional of the density. We have used functionals with two adjustable parameters to det
