The GW approximation




On this website I provide links to key publications concerning the application of the GW approximation and beyond to the interacting homogeneous electron gas and simple metals.
The first link is a postscript-file containing a talk I gave in the Electronic Structure Discussion Group at the 21st of November 2001. It discusses some basic tools of many-body theory, the Hedin equations, the GW approximation and its application to the homogeneous electron gas. For any questions or suggestions please e-mail me.
