Entanglement entropy of free fermions on graphs
Abstract: The von Neumann entropy is key quantity in quantum information and in the investigation of many-body models. In this talk, we will show that tools from algebraic combinatorics and […]

Primordial neutrino asymmetry evolution in the early Universe [remote talk]
Contrary to charged lepton degeneracies which are tightly constrained by the measured baryon-to-photon ratio, the allowed values of the primordial neutrino asymmetries cover a large range. In order to study […]

Renormalisation of integrable sigma-models [remote talk]
Classical integrable sigma-models form an important class of two-dimensional integrable field theories. It is a long standing belief that such models define renormalisable Quantum Field Theories. In this talk, I […]

Feebly-Interacting Particles for flavour and muon g-2 anomalies
Flavourful Feebly-Interacting Particles (FIPs) in the MeV to GeV range have a strong impact on precision frontier observables ranging from rare meson decays to the lepton anomalous magnetic moments. Based […]

From UV to IR and back [Remote talk]
By considering the photon-graviton scattering amplitude at low-energy including loops from the Standard Model, I will argue how we can infer constraints on the UV behaviour of the gravitational scattering […]

Quantum Gravity meets Statistical Physics
In this talk, I will give a description of semi-classical gravity in terms of quantum chaos and statistical physics. I will present the OPE Randomness Hypothesis (ORH), a generalization of […]

A tale of dark matter production
In this talk, I will discuss various possibilities of producing dark matter in the early universe. By describing the transition between an inflationary epoch to a late time cosmology, I will […]

Precision spectroscopy, fundamental constants, and new physics [Colloquium]
High-resolution spectroscopy of the simplest atoms and molecules plays an important role in the determination of fundamental physical constants such as the Rydberg constant or the proton charge radius, and […]
