Quenching 2D Quantum Gravity [PDF]

Physics Letters B, 1994
We simulate the Ising model on a set of fixed random $\phi^3$ graphs, which corresponds to a {\it quenched} coupling to 2D gravity rather than the annealed coupling that is usually considered.

Damaging 2D Quantum Gravity [PDF]

Physics Letters B, 1993
We investigate numerically the behaviour of damage spreading in a Kauffman cellular automaton with quenched rules on a dynamical $\phi^3$ graph, which is equivalent to coupling the model to discretized 2D gravity.

Extended 2d generalized dilaton gravity theories [PDF]

Classical and Quantum Gravity, 2007
We show that an anomaly-free description of matter in (1+1) dimensions requires a deformation of the 2d relativity principle, which introduces a non-trivial center in the 2d Poincare algebra.

An approach to quantum 2D gravity

Physics Letters B, 2023
We consider a model of 2D gravity with the action quadratic in curvature and represent path integrals as integrals over the SL(2,R) invariant Gaussian functional measure.

Extensions of 2D Gravity [PDF]

International Journal of Modern Physics D, 1993
After reviewing some aspects of gravity in two dimensions, it is shown that non-trivial embeddings of sl(2) in a semi-simple (super) Lie algebra give rise to a very large class of extensions of 2D gravity.

Symplectic Structure of 2D Dilaton Gravity [PDF]

Physics Letters B, 1993
We analyze the symplectic structure of two-dimensional dilaton gravity by evaluating the symplectic form on the space of classical solutions. The case when the spatial manifold is compact is studied in detail.

Islands in asymptotically flat 2D gravity [PDF]

Journal of High Energy Physics, 2020
The large-N limit of asymptotically flat two-dimensional dilaton gravity coupled to N free matter fields provides a useful toy model for semiclassical black holes and the information paradox.

Towards unified theory of $2d$ gravity [PDF]

Nuclear Physics B, 1992
We introduce a new 1-matrix model with arbitrary potential and the matrix-valued background field. Its partition function is a $\tau$-function of KP-hierarchy, subjected to a kind of ${\cal L}_{-1}$-constraint.

Wormholes in 2d Horǎva-Lifshitz quantum gravity [PDF]

Physics Letters B, 2021
We quantize the two-dimensional projectable Horǎva-Lifshitz gravity with a bi-local as well as space-like wormhole interaction. The resulting quantum Hamiltonian coincides with the one obtained through summing over all genus in the string field theory ...
