Effects of Gravity and Inlet/Outlet Location on a Two-Phase Cocurrent Imbibition in Porous Media

open access: yesJournal of Applied Mathematics, 2011
We introduce 2D numerical investigations of the problem of gravity and inlet/outlet location effects of water-oil two-phase cocurrent imbibition in a porous medium. Three different cases of side-, top-, and bottom-inlet location are considered.

The Schwarzian theory — origins

open access: yesJournal 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.

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

open access: yesAnnals 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.

COSMOLOGICAL SOLUTIONS IN 2D POINCARÉ GRAVITY [PDF]

open access: yesInternational 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.

2d TQFTs and baby universes

open access: yesJournal 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 ...

Bulk Correlation Functions in 2d Quantum Gravity [PDF]

open access: yesTheoretical and Mathematical Physics, 2006
We compute bulk 3- and 4-point tachyon correlators in the 2d Liouville gravity with non-rational matter central charge c<1, following and comparing two approaches. The continuous CFT approach exploits the action on the tachyons of the ground ring generators deformed by Liouville and matter ``screening charges''.
