On the equivalence of topological and quantum 2D gravity [PDF]
Physics Letters B, 1992 We demonstrate the equivalence of Virasoro constraints imposed on continuum limit of partition function of Hermitean 1-matrix model and the Ward identities of Kontsevich's model. Since the first model describes ordinary $d = 2$ quantum gravity, while the second one is supposed to coincide with Witten's topological gravity, the result provides a strong ...

Quantization of a theory of 2D dilaton gravity [PDF]
Physics Letters B, 1992 We discuss the quantization of the 2d gravity theory of Callan, Giddings, Harvey, and Strominger (CGHS), following the procedure of David, and of Distler and Kawai. We find that the physics depends crucially on whether the number of matter fields is greater than or less than 24.

2D Quantum Gravity and The Miura Map [PDF]
Physics Letters B, 1992 We study the sL(3,C) mKDV string theories. We obtain the flows and the string equations. Using the generalized Miura map, we show that we have an unification of these models with the [P,Q]=Q sL(3,C) KDV ones in the framework of open-closed string ...

2D quantum gravity from quantum entanglement [PDF]
Physical Review Letters, 2010 In quantum systems with many degrees of freedom the replica method is a useful tool to study the entanglement of arbitrary spatial regions. We apply it in a way which allows them to back-react.

Pole-skipping points in 2D gravity and SYK model [PDF]
Journal of High Energy Physics, 2023 We represent the first investigation of pole-skipping on both the gravity and field theory sides. In contrast to the higher dimensional models, there is no momentum degree of freedom in (1 + 1)−dimensional bulk theory.

The Cardy–Verlinde formula for 2D gravity [PDF]
Nuclear Physics B, 2002 We discuss the different bounds on entropy in the context of two-dimensional cosmology. We show that in order to obtain well definite bounds one has to use the scale symmetry of the gravitational theory. We then extend the recently found relation between the Friedmann equation and the Cardy formula to the case of two dimensions.

Symmetries at causal boundaries in 2D and 3D gravity [PDF]
Journal of High Energy Physics, 2022 We study 2d and 3d gravity theories on spacetimes with causal (timelike or null) codimension one boundaries while allowing for variations in the position of the boundary.

Near-horizon quantum dynamics of 4D Einstein gravity from 2D Jackiw-Teitelboim gravity [PDF]
Physical Review D, 2022 We study quantum fluctuations in the lightcone metric of the 4-d Einstein-Hilbert action via dimensional reduction to Jackiw-Teitelboim (JT) gravity. In particular, we show that, in Einstein gravity, the causal development of a region in flat Minkowski ...
