In 2021, THIBAULT DAMOUR's research focused on the following two topics: 1) Effect of the exchange of radiation-type gravitons (rather than those responsible for the Newtonian-type interaction) on the dynamics of a gravitational binary system (e.g. a system of two black holes). The radiation effects are of two types: conservative and dissipative. The control of these effects is important to improve the description of the last orbits of coalescing of binary systems observed by gravitational wave detectors. This research is carried out in collaboration with Donato Bini and others. 2) Study of the hidden symmetries of five-dimensional supergravity related to the

hyperbolic Kac-Moody algebra G 2

++. This study is carried out in collaboration with Philippe Spindel and is being drafted.

HUGO DUMINIL-COPIN is devoting his time to the study of the height function of the six-vertex model. This central model in planar statistical physics is related to a variety of lattice models undergoing a continuous phase transition. The goal of Hugo Duminil-Copin s research is to prove conformal invariance of the six-vertex model, to be able to deduce it for all those related models.
