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…

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…
