Consistent 4-form fluxes for maximal supergravity [PDF]
, 2015 We derive new ansaetze for the 4-form field strength of D=11 supergravity corresponding to uplifts of four-dimensional maximal gauged supergravity. In particular, the ansaetze directly yield the components of the 4-form field strength in terms of the ...

New Advancements in AdS/CFT in Lower Dimensions
Universe, 2021 We review recent developments in the study of the AdS/CFT correspondence in lower dimensions. We start by summarising the classification of AdS3×S2 solutions in massive type IIA supergravity with (0, 4) supersymmetries and the construction of their 2D ...

The exceptional story of massive IIA supergravity [PDF]
, 2016 A bstractThe framework of exceptional field theory is extended by introducing consistent deformations of its generalised Lie derivative. For the first time, massive type IIA super-gravity is reproduced geometrically as a solution of the section ...

Journal of High Energy Physics, 2002 We construct supergravity solutions corresponding to space-like branes in string theory. Our approach is to apply the usual solution generating techniques to an appropriate time-dependent solution of the eleven dimensional vacuum Einstein equations. In this way all SDp-brane solutions are obtained, as well as the NS and M-theory space branes.

On the Non-Abelian U-Duality of 11D Backgrounds
Universe, 2022 In this work, we generalise the procedure of the non-abelian T-duality based on a B-shift and a sequence of formal abelian T-dualities in non-isometric directions to 11-dimensional backgrounds.

Type II supergravity origin of dyonic gaugings [PDF]
, 2016 Dyonic gaugings of four-dimensional supergravity typically exhibit a richer vacuum structure compared to their purely electric counterparts, but their higher-dimensional origin often remains more mysterious.

Physical Review Letters, 2022 Minimal massive gravity in three dimensions propagates a single massive spin-2 mode around an AdS vacuum. It is distinguished by allowing for vacua with positive central charges of the asymptotic conformal algebra and a bulk graviton of positive energy.

Cosmological Constant in SUGRA Models with Degenerate Vacua
Universe, 2019 The extrapolation of couplings up to the Planck scale within the standard model (SM) indicates that the Higgs effective potential can have two almost degenerate vacua, which were predicted by the multiple point principle (MPP). The application of the MPP

Near-AdS2 Spectroscopy: Classifying the Spectrum of Operators and Interactions in
Universe, 2021 We describe holographic properties of near-AdS2 spacetimes that arise within spherically symmetric configurations of N=2 4D U(1)4 supergravity for both gauged and ungauged theories.

Supergravity description of field theories on curved manifolds and a no go theorem [PDF]
, 2000 In the first part of this paper we find supergravity solutions corresponding to branes on worldvolumes of the form Rd×Σ where Σ is a Riemann surface. These theories arise when we wrap branes on holomorphic Riemann surfaces inside K3 or CY manifolds.
