Presentation

Johan Jönsson's research focuses on incorporating spectroscopic calculations in the dynamical mean field theory.

Dynamical mean field theory gives a good description of the electronic structure of materials where electronic correlations become important, so called strongly correlated materials.

Spectroscopy is used in experiments in order to determine a large number of different properties and, the spectroscopic properties of a material is determined by it's electronic structure. It therefore becomes important to have a good description of the electronic structure in order to properly calculate the spectroscopic properties.
