Implicit infinite lattice summations for real space ab initio correlation methods
Martin Albrecht
We suggest a local wave function based ab initio correlation method for infinite periodic systems, which can describe both the near range as well as the long range correlation effe…

Ab initio Green's function formalism for band structures
Christian Buth, Uwe Birkenheuer, Martin Albrecht +1
Using the Green's function formalism, an ab initio theory for band structures of crystals is derived starting from the Hartree-Fock approximation. It is based on the algebraic diag…

Towards a frequency independent incremental ab initio scheme for the self energy
Martin Albrecht
The frequency dependence of the self energy of a general many--body problem is identified as a main obstacle in correlation calculations based on local approaches. A frequency inde…
