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!
Javi
