Talk

In order to increase our understanding of the black hole information loss paradox
it appears mandatory to incorporate backreaction effects into the black hole evaporation process. We propose a natural extension of the well known linear,
backreaction free, perturbation theory of black holes. The extended framework
is based on the reduced phase space approach and therefore is able to...

13. Entanglement of fields in evaporating black holes

Understanding the quantum information aspects of fields in gravitational collapse scenarios remains an open issue to date. Here, we present a conservative QFT study about the entanglement structure of the Hawking effect in evaporating black holes. For this purpose, first we review the known concept of Hawking partners, as being the field modes that are entangled with, and thus purify, the...

17. Is Planckian discreteness observable in cosmology?

Alejandro Perez (Zoom) ( Centre de Physique Théorique )

A Planck scale inflationary era—in a quantum gravity theory predicting discreteness of quantum geometry at the fundamental scale—produces the scale invariant spectrum of inhomogeneities with very small tensor-to-scalar ratio of perturbations and a hot big bang leading to a natural dark matter genesis scenario. In this talk I evoke the possibility that some of the major puzzles in cosmology...
