The two-sphere partition function from timelike Liouville theory at three-loop order

Journal of High Energy Physics, 2022
While the Euclidean two-dimensional gravitational path integral is in general highly fluctuating, it admits a semiclassical two-sphere saddle if coupled to a matter CFT with large and positive central charge. In Weyl gauge this gravity theory is known as

New evidence on the geologic setting of Medjerda Valley plain (northern Tunisia) from integrated geophysical study of Triassic evaporite bodies

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.

Wormholes in 2d Horǎva-Lifshitz quantum gravity

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 ...

The Schwarzian theory — origins

Journal of High Energy Physics, 2018
In this paper we further study the 1d Schwarzian theory, the universal low-energy limit of Sachdev-Ye-Kitaev models, using the link with 2d Liouville theory.

2d TQFTs and baby universes

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 ...

COSMOLOGICAL SOLUTIONS IN 2D POINCARÉ GRAVITY [PDF]

International Journal of Modern Physics D, 1994
The 2D model of gravity with zweibeins ea and the Lorentz connection one-form [Formula: see text] as independent gravitational variables is considered. The solutions of classical equations of motion which can be interpreted as cosmological ones are studied.

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 ...

2D behavior of Gravity at Large Distances

, 2023
We show that the entropy or information flow of a gravitational system constrains the dependence of gravitational force on radial distance r which for very large r is equivalent to gravity in two dimensions. This explains the "origin" of dark matter and provides a natural solution to the problem of flat rotation curves of galaxies at very large ...
