Description

The aim of this workshop is to discuss the advances in the theoretical and computational treatment of optical and dielectric spectroscopy in the framework of many-body-perturbation-theory (MBPT).

A special emphasis will be placed on the assessment of ten years of the Bethe-Salpter Equation (BSE) method presenting its achievements, developments, applications, advantages and drawbacks in comparison to the more recent developments of time-dependent density-functional theory (TDDFT).

Discussions will be stimulated on the complementarity of the two methods and on the future of BSE with respect to TDDFT. The state of the art implementations of these ab initio methods into existing numerical codes will be presented in this meeting.

Speakers from leading international groups will give an in-depth overview of current research activities in MBPT and place recent results into context. The meeting aims at providing an informal atmosphere for stimulating discussions between researchers working in this exciting field. Young researchers (Ph.D. students and postdocs) are particularly encouraged to present their work.
