Density functional theory in electronic structure calculations
Density functional theory is the workhorse for electronic structure calculations, both for molecular and extended systems. In this talk I will give a brief overview over the many-electron problem, how ideas emerged to solve it using energy densities, and how the field was put onto a solid theoretical footing by Hohenberg, Kohn, and Sham. If time permits, I will present Kato?s theorem on density derivative singularities in Coulombic systems.
This is a roughly weekly series of didactical blackboard talks focussing on some theoretical aspect of Condensed Matter, Biological, and Statistical Physics..
