Liouville and JT quantum gravity - holography and matrix models

Regular Seminar Thomas Mertens (GENT U.)

room Zoom
abstract:

In this talk, we will discuss recent progress in understanding quantum gravity amplitudes (partition function and boundary correlation functions) in Liouville gravity, and how they limit to Jackiw-Teitelboim (JT) correlators. We also discuss multiboundary and higher genus amplitudes. We focus on two main results: the Liouville gravity answers look like q-deformations of the JT answers, and Liouville gravity can be related to a 2d dilaton gravity with a sinh dilaton potential. We end with discussions on supersymmetric extensions and work in progress. Based largely on arXiv:2006.07072 and 2007.00998​. [For the Zoom link, please email to: alejandro.cabo_bizet@kcl.ac.uk ]
