Non-adiabatic transitions in the density matrix formalism
Pasquale Di Bari, Shreya Pandit, Ye-Ling Zhou
We show that a density matrix formalism provides a useful description of non-adiabatic transitions in two-state quantum systems. Compared to a traditional Hamiltonian formalism, ev…
Boomerang mechanism explaining the excess radio background
Bhupal Dev, Pasquale Di Bari, Ivan Martinez-Soler +1
We propose a boomerang mechanism for the explanation of the excess radio background detected by ARCADE 2. In an early stage of the Universe, at a temperature in the range $\sim…
How neutrinos could help solving cosmological anomalies and tensions
Pasquale Di Bari
In this talk I discuss how neutrinos might help solving or alleviating different anomalies and tensions in cosmology. Invisible decays of the heaviest relic neutrinos might provide…
-inspired leptogenesis
Pasquale Di Bari
In the first part of the talk, I review general properties of -inspired leptogenesis. This high-scale leptogenesis scenario is based on the simple assumption that the neutr…
Testing an unstable cosmic neutrino background
Pasquale Di Bari
I discuss how different cosmological observations can test the possibility that neutrinos might be unstable on cosmological times, resulting into an unstable cosmic neutrino backgr…
