Description
The goal of this online seminar is to bring Theoretical Physics closer to experiment and discuss current topics in high energy theory, cosmology & astrophysics. This intends to renew and continue the tradition of "Proca seminars" (1946-1955) initiated by Alexandru Proca in Paris.
The seminar is 1h long followed by a questions session with no exact time limit, to allow many people to ask questions.
The list of the talks & zoom links is also found at inspirehep.net.

Title: Geometrical formulations of gravity and its coupling to matter
Speaker: Prof. Lavinia Heisenberg (Zurich, ETH)
Date: Thursday 28 July 2022, 14:00h CEST/Paris time, (15:00h EEST; 21:00h Tokyo time)

Abstract:
I will first introduce 3 alternative but completely equivalent formulations of GR, where gravity is assigned to either curvature, or torsion or to non-metricity (mentioning extensions of GR on the way). I will then discuss how matter can couple to these different geometries and whether the minimal coupling principle can be preserved.
