Spectral Geometry of Black Holes in 4D Gauged Supergravity

open access: yesUniverse, 2021
In this work we show that the area of the event horizon of the Chong–Cvetic–Lu–Pope black hole can be reconstructed in terms of the spectra of the Laplacian on the event horizon.

dS2 supergravity

open access: yesJournal of High Energy Physics, 2023
Abstract We construct two-dimensional supergravity theories endowed with a positive cosmological constant, that admit de Sitter vacua. We consider the cases of $$ \mathcal{N} $$ N = 1 as well as $$ \mathcal{N} $$ N = 2 supersymmetry, and couple the supergravity ...

Quintessence and supergravity

open access: yesPhysics Letters B, 1999
In the context of quintessence, the concept of tracking solutions allows to address the fine-tuning and coincidence problems. When the field is on tracks today, one has $Q\approx m_{\rm Pl}$ demonstrating that, generically, any realistic model of quintessence must be based on supergravity.

Solution of the deformed Schwarzschild metric by the Yang-Baxter equation

open access: yesҚарағанды университетінің хабаршысы. Физика сериясы, 2019
In this article, an open-closed string map formulated by Seiberg & Whitten was used to solve problems of generalized supergravity, including the deformed Schwarzschild metric.

Euclidean supergravity [PDF]

open access: yesJournal of High Energy Physics, 2017
Supergravity with eight supercharges in a four-dimensional Euclidean space is constructed at the full non-linear level by performing an off-shell time-like reduction of five-dimensional supergravity. The resulting four-dimensional theory is realized off-shell with the Weyl, vector and tensor supermultiplets and a corresponding multiplet calculus ...

Newton-Cartan supergravity with torsion and Schrödinger supergravity [PDF]

open access: yesJournal of High Energy Physics, 2015
We derive a torsionfull version of three-dimensional N=2 Newton-Cartan supergravity using a non-relativistic notion of the superconformal tensor calculus. The "superconformal" theory that we start with is Schrödinger supergravity which we obtain by gauging the Schrödinger superalgebra.

Novel Free Differential Algebras for Supergravity

open access: yesUniverse, 2023
We develop the theory of Free Integro-Differential Algebras (FIDA) extending the powerful technique of Free Differential Algebras constructed by D. Sullivan. We extend the analysis beyond the superforms to integral- and pseudo-forms used in supergeometry.
