Abstract:
A large class of two-dimensional dilaton-gravity theories in asymptotically AdS2 spacetimes are holographically dual to a matrix integral, interpreted as an ensemble average over Hamiltonians. Viewing these theories as Jackiw-Teitelboim gravity with a gas of defects, I will show how to extend this duality to a broader class of dilaton potentials compared to previous work by including conical defects with small deficit angles. In order to do this, I show that these theories are equal to the large p limit of a natural deformation of the (2, p) minimal string theory.
