Hi everybody,
This *Friday 30th at 11:30 in Aula C* we will keep on going with the
cordas-club. In this occasion the discussion will be led by *Alejandro
Vilar* who will talk to us about the* holography of information*.
*Abstract:* We will review the (somewhat controversial) proposal of
"holography of information", which states that in a theory of quantum
gravity a copy of all the information on a Cauchy slice is available near
its boundary. The idea will be to discuss some of the low-energy hints
employed to defend this proposal. If time permits, we will also discuss the
relation of these ideas with recent braneworld models of black hole
evaporation in which the asymptotic bath is coupled to dynamical gravity.
*References:*
A recent review which presents these ideas (and which will guide the
discussion) are the first 5 sections of:
https://arxiv.org/abs/2012.05770
More detailed references which expand on the arguments of the review are:

Finally, the braneworld model of evaporation is presented in:

*Covid restrictions:* The room is big and we can safely keep a distance
from each other, but of course all protocols are to be respected and masks
will be mandatory for all attendants.
*Broadcast details*
The meeting will be held in the open source platform JITSI
