The holographic principle, and how to force neutrinos to obey it

I will motivate the holographic principle and explain why it already appears at the level of classical GR. I will then present results from our recent paper https://arxiv.org/abs/2402.11016 where we construct a fermionic quantum field obeying this principle and derive observational consequences from that. In particular, I will show how these consequences hold up compared to actual observations of cosmic neutrino flux.
