Many-Body Theory: Nuclear Physics Meets Quantum Chemistry

24 Aug 2026, 09:00 → 4 Sept 2026, 18:00 Europe/Berlin

2413/2-430 - MITP Seminar Room (MITP - Mainz Institute for Theoretical Physics, Johannes Gutenberg University Mainz)

Registration closes 24 April 2026 11:59 P.M. CET.

Our interdisciplinary program will explore state-of-the-art developments in quantum many-body theory at the intersection of nuclear physics and quantum chemistry.

The aim of the program is to stimulate discussion and cross-fertilization between the communities of nuclear theory and quantum chemistry with the goal of triggering new interdisciplinary collaboration. To this end, we will invite experts working on a variety of many-body frameworks, e.g., coupled-cluster, Green’s functions theory, and density functional theory. Lectures by renowned scientists will provide participants with an introduction to the distinct phenomenology of atomic nuclei and molecules.

The program will address two key topics of high relevance to both nuclear and electronic-structure simulations of many-particle systems:

• In the first week, the description of strongly correlated many-body systems that are characterized by a breakdown of the mean-field description;
•  In the second week, the modeling of response functions in nuclei and molecules subjected to external probes.

The format is meant to grant plenty of time for informal discussions and to stimulate new collaborations and projects.
