Many-body perturbation theories in modern quantum chemistry and nuclear physics

26-30^th March                              PROGRAM (updated 21^st March)  ESNT_workshop_MBPT_2018v21march.pdf

 

 

Organizers:  A. Tichai (CEA, ESNT, contact), E. Giner (LCT, Université P. et M. Curie), T. Duguet (CEA, DPhN-contact)

 

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.
