Challenges in modelling correlated electronic matter — •Roser Valenti — Institute of Theoretical Physics, Goethe University Frankfurt, Frankfurt, Germany

The microscopic modelling of correlated electronic matter from first principles poses a fundamental theoretical challenge due to the many-body character of the systems. In recent years there have been a few internationally coordinated efforts in theoretical method development to generate a common platform of benchmarked software tools including dynamical mean field theory and extensions.

In this talk I will present some of the challenges we face in such an endeavour and illustrate them with some examples on models and materials.
