Nuclear Physics Division

On behalf of the "Espace de Structure et de réactions Nucléaires Théorique" (ESNT), the workshop entitled: "Many-body perturbation theories in modern quantum chemistry and nuclear physics" will be held in March 26th -30th, 2018 at CEA-Saclay, b.703 (Orme-les-Merisiers site).

The scope of the proposed interdisciplinary workshop is to bring together researchers from quantum chemistry and nuclear physics to elaborate on the use of many-body perturbation theories (MBPT) for the description of fermionic many-body quantum systems.

The goals of the workshop are to:
1. educate nuclear physicists about the relevance of MBPT methods in modern quantum many-body calculations.
2. exchange ideas regarding state-of-the-art MBPT methods between quantum chemists and nuclear physicists.
3. identify the systems, observables and situations for which perturbative methods are appropriate.
4. discuss the merits and the efficiency of the various strategies to treat near-degenerate and degenerate systems via perturbative methods.
In order to facilitate the understanding and involvement of young theorists and experimentalists as well as to lay a common ground for quantum chemists and nuclear theorists, lectures (~1h15) on (i) the fundamentals of many-body perturbation theory, (ii) the historical trends and future directions of MBPT, (iii) the introduction to multi-reference approaches, (iv) the concept of symmetry breaking and restoration in the context of MBPT and (v) basic properties of nuclear interactions in connection to MBPT calculations, will be given at the beginning of the workshop.
