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 […]

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 Hilbert spaces on both sides of the correspondence.  We review these issues and show how the Berry phase, a geometrical phase encoding information about topology, […]

[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 […]
