The Grande Conférence is the annual symposium of the RQMP. This day is focused on sharing scientific knowledge and is an opportunity to network. 2022 program was based on Low-dimensionnal materials dimension, a major conference by Eva Andrei (Rutgers University), conferences by our members Antonella Badia, Tami Pereg-Barnea, David Sénéchal, and Stéphane Kena-Cohen, and a poster session to see the work of our students.
