dc.description.abstract
Susceptibilities and optical conductivity are examples of two-particle response functions that are the key quantities for connecting theoretical predictions with experimental results. It can however become highly non-trivial to calculate them, especially in cases when vertex corrections are important. In my talk I will explain what vertex corrections to response functions are and when they become important. I will then present diagrammatic methods of their computation with the focus on parquet equations. I will show results for a special type of vertex corrections to optical conductivity, the pi-tons [1], that are present in systems with antiferromagnetic or charge density wave fluctuations. These vertex corrections lead to a displaced Drude peak in correlated metals [2].
