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 […]

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 […]
Axion is a light particle arising in QCD as a solution to the strong CP problem and is considered to be one of the most promising dark matter candidate with […]

Within the AdS/CFT correspondence, the entanglement properties of the CFT are related to wormholes in the dual gravity theory. This gives rise to questions about the factorisation properties of the […]
Abstract: We consider an effective field theory framework with three Standard Model (SM) gauge singlet right-handed neutrinos and an additional SM gauge singlet scalar field. The framework generates eV masses […]
The Lambda-cold-dark-matter (LCDM) model has established itself as a fantastic (yet parametric) concordance model able to adjust a wide variety of cosmological observables — CMB, BBN, Large Scale Structure (LSS) […]
I will discuss string theory compactifications where a large number of moduli is stabilized by fluxes. I will first present a conjecture which rules out the stabilization of all complex-structure moduli […]
This is a meeting on topics related to string and field theory, between members of nearby institutions: IP2I (CNRS, UCBL), Lyon LAPTh (CNRS, USMB), Annecy LPENSL (CNRS, ENSL), Lyon More information can be found on the AnLy webpage. For this second edition, the meeting will take place in IP2I, Lyon, on the 19/05/22. Talks will […]
We discuss flux compactifications of Type IIA supergravity on G2 spaces with smeared O2/O6-planes down to three dimensions. We start by presenting the setup of allowed fluxes, the internal geometry, the equations of motion and after compactification we achieve N=1 AdS3 vacua with scale that can be parametrically decoupled from the KK modes. The solutions […]
