Effective gravitational action for 2D massive fermions
Journal of High Energy Physics, 2021 We work out the effective gravitational action for 2D massive Euclidean fermions in a small mass expansion. Besides the leading Liouville action, the order m 2 gravitational action contains a piece characteristic of the Mabuchi action, much as for 2D ...

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

Joint Inversion of 2D Gravity Gradiometry and Magnetotelluric Data in Mineral Exploration
Minerals, 2019 We have developed a mineral exploration method for the joint inversion of 2D gravity gradiometry and magnetotelluric (MT) data based on data-space and normalized cross-gradient constraints.

The two-sphere partition function in two-dimensional quantum gravity
Journal of High Energy Physics, 2021 We study the Euclidean path integral of two-dimensional quantum gravity with positive cosmological constant coupled to conformal matter with large and positive central charge.

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

Anomaly induced effective actions in even dimensions and reliability of s-wave approximation [PDF]
, 1999 The reduction of 4d matter-gravity theory to $S_2$, $H_2$ or $R_2$ leads to effective 2d dilatonic gravity with dilaton coupled matter. Spinors give the exceptional example of the theory which is conformally invariant in 4d as well as in 2d, after ...

The price of curiosity: information recovery in de Sitter space
Journal of High Energy Physics, 2021 Recent works have revealed that quantum extremal islands can contribute to the fine-grained entropy of black hole radiation reproducing the unitary Page curve.
