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 […]

Searching for axions in the sky and the lab
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 […]

Berry phases, wormholes and factorization in AdS/CFT [Remote talk]
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 […]

[Journal Club] Right-handed neutrinos, TeV scale BSM neutral Higgs boson, and FIMP dark matter in an EFT framework
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 of light neutrinos via the seesaw mechanism and accommodates a feebly interacting massive particle (FIMP) as a dark matter candidate. Two of the gauge singlet […]

CMB, LSS and the distance ladder: cosmic discordance? [Remote talk]
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 […]

The Tadpole Problem [Remote talk]
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 […]
