Hi everybody, The result of the poll seems clear, so we will meet this *Friday 5th at 11:30 in Aula C* to finish with the topic of last Friday. In this session I will sketch the derivation of the thermal partition function of JT gravity and (hopefully) its equivalence to a RMT ensemble. *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 sketch the derivation of the thermal partition function of JT gravity and (hopefully) its equivalence to a RMT ensemble. *References: * https://arxiv.org/abs/1711.08482 and https://arxiv.org/pdf/1606.01857.pdf for some JT basics and connections to SYK. https://arxiv.org/abs/1903.11115 for the calculation of the path integral and the proof of its equivalence to RMT. *Zoom details* Tema: Cordas Club Hora: 5 mar. 2021 11:30 a. m.
