Title : Recent developments in JT gravity

Two-dimensional Jackiw-Teitelboim (JT) gravity is a useful toy model
to study various aspects of quantum gravity and holography. In a
recent paper by Saad, Shenker and Stanford, it was shown that JT
gravity is holographically dual to a certain double-scaled matrix
model. This is an example of the holography involving the ensemble
average, where the Hamiltonian of the boundary theory becomes the
random matrix. This in particular implies that the correlator of two
partition functions includes the contribution of spacetime wormhole
connecting the two asymptotic boundaries. In this talk I will give an
overview of the recent developments of JT gravity matrix model.

The colloquium will be held via ZOOM.
