Ab initio studies of electronic excitations using many-body perturbation theory

Rex Godby (University of York, UK), Lucia Reining (Ecole Polytechnique, Palaiseau, France) and Steven Louie (University of California at Berkeley, and Lawrence Berkeley National Lab, Berkeley, California, USA) will be the speakers in the next instalment of the CECAM-MARVEL Classics in molecular and materials modelling, dedicated to ab initio studies of electronic excitations using many-body perturbation theory.

In this series, methods that have become fundamental tools in computational physics and chemistry will be presented by their originators at a level appropriate for master and graduate students. The lectures will be followed by an interview with the presenters: we’ll ask them to recall for us the period, problems, people and circumstances that accompanied the creation of milestone methods and algorithms that we now routinely use. 

We hope that you will be able to join us and share with us this unusual and interesting opportunity to learn first hand from pioneers who have contributed significantly to our field and to get to know better the history and anecdotes behind work that is now recorded in books.
