Cordas Club next Friday 26 at 11:30
by Javier Martin
Hi everybody,
Due to some overlappings, the date for the first session of the Cordas Club
has been changed to next *Friday 26 at 11:30.* It will take place in *Aula
C* (the one in the left corner as you enter IGFAE) for those who can come
and will also be broadcasted by Zoom (I will send the email a few minutes
before the session starts) for those that want to connect telematically.
As I said, the discussion will be lead by me and will talk about some
simple model in 2d gravity
*Title: *JT gravity and its connection to Random Matrix Theory
*Abstract:* Jackiw-Teitelboim (JT) gravity is a very simple dilaton-gravity
toy model in two dimensions. For a long time, little attention has been put
into this and other similar models that are very far from the real-world
gravity but recent developments have brought it back into focus in the high
energy community. Its relation with the quantum-chaotic model of
Sachdev-Ye-Kitaev (SYK) is one of such developments, but an even stronger
equivalence has been found with some random matrix theory ensembles.
Indeed, the JT model is the first gravity theory for which the exact
Euclidean path integral has been performed exactly at all loops, a fact
that by itself makes this theory worth studying. In this session I will try
to review (or at least scratch the surface) of the main aspects of this
model and (time-permitting) will sketch the computation of the path
integral and its equivalence with RMT.
*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.
See you there!

Cordas Club
by Javier Martin
Hi everybody!
Despite all the obstacles in these boring pandemia times, I have been
thinking that it would be nice to try and start a journal club for the
"string" group of the IGFAE. I guess everybody is familiar with the
concept, but the idea is to meet every two weeks and have informal
discussions about anything that we consider interesting. This could mean
discussing recent papers, old ones, presenting our own work, etc.
The concrete topics are of course not constrained and can be as wide as our
research interests are. Hopefully this will be useful to learn topics that
are a little out of each one's expertise and help us get in contact with
each other's interests.
Regarding the mechanics of the sessions, I suggest that we try to design
them as interactive as possible meaning that *we must think of the
"speaker" as leading a discussion rather than presenting a seminar*. Also
along this line, the use of a blackboard (physical or electronic via tablet
in zoom) is greatly encouraged over slides presentations.
The logistics is something we can all decide. I propose to do it every two
Wednesdays at 12:00, for example. If someone has a problem with this
timetable, please let me know and we can try to find a better time that
suits everybody.
For the first session next week, I myself will lead a discussion about *JT
gravity (and its connection to Random Matrix Theory)*, which is a topic
that has attracted some attention along the last few years (I will send a
later email with more details). If there is interest in the topic I am also
willing to extend it to a second session, but I would need another speaker
for the third one. If anybody is interested in doing so, please send me an
email :)
I hope you find my proposal interesting and we manage to get ahead with it
with everybody's engagement.
Cheers,
Javi
