Quasiparticle Calculations for Point Defects on Semiconductor Surfaces
Magnus Hedstrom, Arno Schindlmayr, Matthias Scheffler
We discuss the implementation of quasiparticle calculations for point defects on semiconductor surfaces and, as a specific example, present an ab initio study of the electronic str…
Self-consistency and vertex corrections beyond the GW approximation
Arno Schindlmayr
The good performance of the GW approximation for band-structure calculations in solids was long taken as a sign that the sum of self-energy diagrams is converged and that all omitt…
Diagrammatic self-energy approximations and the total particle number
Arno Schindlmayr, P. Garcia-Gonzalez, R. W. Godby
There is increasing interest in many-body perturbation theory as a practical tool for the calculation of ground-state properties. As a consequence, unambiguous sum rules such as th…
Exchange-correlation kernels for excited states in solids
Krzysztof Tatarczyk, Arno Schindlmayr, Matthias Scheffler
The performance of several common approximations for the exchange-correlation kernel within time-dependent density-functional theory is tested for elementary excitations in the hom…
Decay properties of the one-particle Green function in real space and imaginary time
Arno Schindlmayr
The decay properties of the one-particle Green function in real space and imaginary time are systematically studied for solids. I present an analytic solution for the homogeneous e…
Universality of the Hohenberg-Kohn functional
Arno Schindlmayr
We comment on a recent article by H. L. Neal [Am. J. Phys. 66, 512 (1998)], in which an analytic expression for the Hohenberg-Kohn functional was derived for one-dimensional two-pa…
