The No-Hair Conjecture in 2D Dilaton Supergravity [PDF]
, 1993 We study two dimensional dilaton gravity and supergravity following hamiltonian methods. Firstly, we consider the structure of constraints of 2D dilaton gravity and then the 2D dilaton supergravity is obtained taking the squere root of the bosonic ...

CANONICAL APPROACH TO 2D INDUCED GRAVITY [PDF]
Modern Physics Letters A, 2001 Using canonical method the Liouville theory has been obtained as a gravitational Wess–Zumino action of the Polyakov string. From this approach it is clear that the form of the Liouville action is the consequence of the bosonic representation of the Virasoro algebra, and that the coefficient in front of the action is proportional to the central charge ...

Journal of High Energy Physics, 2021 In this work, we extend the 2d topological gravity model of [1] to have as its bulk action any open/closed TQFT obeying Atiyah’s axioms. The holographic duals of these topological gravity models are ensembles of 1d topological theories with random ...

Physics Letters B, 1990 Abstract We consider a formulation of nonperturbative two-dimensional quantum gravity coupled to a single bosonic field (d = 1 matter). Starting from a matrix realization of the discretized model, we express the continuum theory as a double scaling limit in which the 2D cosmological constant g tends towards a critical value gc, and the string ...

Softening transitions with quenched 2D gravity [PDF]
Nuclear Physics B - Proceedings Supplements, 1997 We perform extensive Monte Carlo simulations of the 10-state Potts model on quenched two-dimensional $ ^3$ gravity graphs to study the effect of quenched connectivity disorder on the phase transition, which is strongly first order on regular lattices.

Entanglement dynamics in 2D CFT with boundary: entropic origin of JT gravity and Schwarzian QM [PDF]
Journal of High Energy Physics, 2018 A bstractWe study the dynamics of the geometric entanglement entropy of a 2D CFT in the presence of a boundary. We show that this dynamics is governed by local equations of motion, that take the same form as 2D Jackiw-Teitelboim gravity coupled to the ...

Annals of Geophysics, 2015 Integrated gravity, two dimensional (2D) seismic and field data (lithostratigraphy and tectonic deformations) help to understand the structural setting of the Triassic evaporites in the Atlas Mountains of northern Tunisia.

2D Extremal Black Holes as Solitons [PDF]
, 1998 We discuss the relationship between two-dimensional (2D) dilaton gravity models and sine-Gordon-like field theories. We show that there is a one-to-one correspondence between the solutions of 2D dilaton gravity and the solutions of a (two fields ...

Soluble models in 2d dilaton gravity [PDF]
, 1995 A one-parameter class of simple models of two-dimensional dilaton gravity, which can be exactly solved including back-reaction effects, is investigated at both classical and quantum levels.
