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 […]

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 […]

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) & SN1a most notably.  However as the precision of the data has increased over the past few years, a number of predictions of the LCDM […]

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 in F-theory at a generic point in moduli space by fluxes that satisfy the tadpole cancellation condition. Evidence for this conjecture comes from studying K3xK3 compactifications using […]
