Assessment of the GW approximation using Hubbard chains
Thomas J. Pollehn, Arno Schindlmayr, R. W. Godby
We investigate the performance of the GW approximation by comparison to exact results for small model systems. The role of the chemical potentials in Dyson's equation as well as th…

Influence of Dynamics on Magic Numbers for Silicon Clusters
A. R. Porter, R. W. Godby
We present the results of over 90 tight-binding molecular-dynamics simulations of collisions between three- and five-atom silicon clusters, at a system temperature of 2000K. Much t…

Systematic vertex corrections through iterative solution of Hedin's equations beyond the GW approximation
Arno Schindlmayr, R. W. Godby
We present a general procedure for obtaining progressively more accurate functional expressions for the electron self-energy by iterative solution of Hedin's coupled equations. The…
