Sébastien Clesse
I'm interested by Cosmic Inflation, Primordial Black Holes as Dark Matter, Modified Gravity, cosmological constraints with future experiments (Euclid, SKA, CORE,...).
Disrael Dacunha
I work on searches for physics beyond the standard model. Given that a
large class of models describing physics beyond the standard model predicts the appearance of topological
defects, I study the consequences of these phenomena in the large scale structure (LSS) of the universe. My
work involves performing numerical computations that simulate these effects to find optimal statistics that
extract the signal from the topological defects. The primary goal of this study is to favor or discard classes
of models that extend the standard model. I used various numerical computational
tools, such as N-Body simulation (CUBEP3M, Gadget, PKDGRAV3, and PICOLA) and data analysis (Curvelab, S2let).

Drazen Glavan
My research interests lie in the overlap of non-equilibrium quantum field theory and cosmology. In particular, my research focuses on quantum loop effects in primordial inflation, perturbative quantum gravity, and warm inflation, both from the formal and phenomenological approach.
Thibaut Grouy
On the one hand, in the continuation of my thesis, I intend to study orbital integrals on pseudo-Riemannian symmetric spaces and totally geodesic Radon transforms on Lorentzian symmetric spaces. First, I will focus on the asymptotic behaviour of orbital integrals on Cahen-Wallach spaces at their singularities. This could help me to determine the invariant eigendistributions in the realm of harmonic analysis. The aim is to compute the explicit Plancherel formula on these spaces when it is possible. Next, I will study the invertibility of totally geodesic Radon transforms.
On the other hand, I intend to study star-products through the prism of Radon-type transforms on symmetric spaces.

My aim is to deeper understand algebraic categorical properties such as the Mal'tsev, unital or semi-abelian properties; in particular via some embedding theorems or preservation under the cofiltered limit completion. I am also interested in internal groupoids, weak equivalences and their bicategory of fractions as well as in finiteness spaces and generalized rings of power series.
Alexandre Lazarescu
I am a post-doctoral researcher in the field of non-equilibrium
statistical physics, specialised in large deviation theory and
interacting particle models. I completed my PhD in 2013 at the
Institut de Physique Théorique (CEA Saclay), where I worked on the
large deviations of the Asymmetric Simple Exclusion Process (ASEP). I
then worked as a postdoc at the Instituut voor Theoretische Fysica (KU
Leuven) and the University of Luxembourg, and at the Centre de
Physique Théorique in Ecole Polytechnique, before coming to the GPP
group at IRMP. My topics of interests include large deviations and
hydrodynamic limits of interacting particle systems far from
equilibrium, exactly solvable models and their combinatorial
structure, quantum integrability methods (as applied to exactly
solvable driven interacting particle systems, such as the ASEP), and
more general properties of rare events in non-equilibrium statistical
models.

Alexi Morin-Duchesne
My field of research is in statistical mechanics and quantum field theory. I am interested in classical and quantum integrable systems defined on a lattice, and in particular in models defined in terms of nonlocal degrees of freedom, or with Boltzmann weights that are complex: the XXZ spin chains, the dense and dilute loop models, the dimer model, the six-vertex model, etc. At criticality, these models are described by conformal field theories (CFT). I study their algebraic structures and their exact solutions, which are accessible thanks to the techniques of integrability. Because of the nonlocal degrees of freedom, these models are described by representations of the Virasoro algebra that are indecomposable yet reducible. Their correlation functions have logarithmic corrections to the usual power-law dependence, and their CFTs are said to be logarithmic. My current FNRS research project is “Algebraic structures and logarithmic correlation functions in integrable statistical models”.

I am a high energy physicist and collider theorist. My primary research focuses on understanding the origin of tiny, nonzero neutrino masses and tests of neutrino mass models (Seesaw models) at collider experiments, such as the Large Hadron Collider. This includes extended gauge sectors (LR-Symmetric, GUT models), scalar sectors (SU(2)L doublets and triplets), and fermionic sectors (SU(2)L singlets and triplets). I have a particular interest in collider signatures involving initial-state electroweak vector bosons (vector boson fusion/scattering) and the impact of (resummed) QCD corrections on (new physics) collider processes. This includes resummation in the context of perturbative QCD and SCET.

Sandrine Brasseur
The goal of my research is to contribute to the rigorous analysis of elliptic two-dimensional integrable models along their combinatorial line. Over the years, these statistical mechanics models have been shown to exhibit rich
analytic and algebraic structures, as well as surprising links to combinatorics. Yet, to this day, many of their aspects remain either conjectural or plainly unexplored. I focus my study on the eight-vertex model and related systems such as the 8VSOS model and the XYZ spin chain, as well as their higher-spin generalisations. One of my central aims is to address conjectures and open questions about the ground state of the XYZ spin chain along its combinatorial line for various boundary conditions. I am also interested in obtaining exact finite-size expressions for some interesting physical quantities. Ultimately, the analysis of their scaling limits for large systems will lead me to establish links with quantum field theory models in the continuum.

François Renaud
My PhD research concerns higher categorical Galois theory in the context of certain algebraic structures of interest called quandles (a notion of symmetry which is used in knot theory and geometry). The category of quandles is algebraic by nature, but features interesting geometrical properties. This provides an interesting context for the study and illustration of higher categorical Galois theory and related meaningful notions of homotopy. Key words: higher categorical Galois theory, racks and quandles, centrality, commutators, higher coverings.
