This edition of the correlation meeting takes place at the Ecole Polytechnique, 25-26 November 2025.
[This meeting will be followed by the ETSF RTL's meeting on 27 November].
This discussion meeting is dedicated to the first-principles treatment of electronic correlation, aiming to assess the true limit of current approaches, identify common "grand challenges", and stimulate further developments.
Following our tradition, the meeting will consist of short talks (≈10 minutes) proposed by participants, followed by longer (up to 1 hour) discussions.
In the International Year of Quantum Science, we will particularly discuss specific aspects of electron correlation:
- excitons, coherent superposition of many-body quantum states, and their (de-)localization
- non-classical observables, pair densities and density matrices
- virtual excitations, both in dynamical screening and in emergent resonant spectroscopies
- non-locality in the response function and connection to quantum weights and Fisher information
Program to be announced.

How to reach us:
The event takes place in the BEM (Bâtiment Enseignement Mutualisé) building (see below for a map), 3rd floor (Room 4006). You can reach Palaiseau via RER B. You can either:
- Get off at Lozère
- Take the Sentier de l'Ecole Polytechnique and walk up to the campus (5 minutes for trained walkers, 15 min for old folks :-).
- Follow the map below for the last few hundred meters.
- Get off at Massy-Palaiseau
- Take the Bus 4606 or 5154 and get off at Polytechnique-Lozere stop (8 minutes).
- Follow the map below for the last few hundred meters.
