Unimodular vs nilpotent superfield approach to pure dS supergravity
, 2021 Recent progress in understanding de Sitter spacetime in supergravity and string theory has led to the development of a four dimensional supergravity with spontaneously broken supersymmetry allowing for de Sitter vacua, also called de Sitter supergravity.

Supersymmetric dS4 solutions in D = 11 supergravity
Journal of High Energy Physics, 2022 The necessary and sufficient conditions for warped product dS4 solutions in D = 11 supergravity to be supersymmetric are determined. The Killing spinor is associated with two possible stabilizer groups, SU(3) and G2.

Non-Lorentzian IIB supergravity from a polynomial realization of SL(2, ℝ)
Journal of High Energy Physics, 2023 We derive the action and symmetries of the bosonic sector of non-Lorentzian IIB supergravity by taking the non-relativistic string limit. We find that the bosonic field content is extended by a Lagrange multiplier that implements a restriction on the ...

De sitter magnetic black hole dipole with a supersymmetric horizon
Journal of High Energy Physics, 2021 We find a new non BPS solution in N = 2 D = 4 gauged supergravity coupled to U(1) gauge fields and matter. It consists in a closed universe with two extremal black holes of equal size, surrounding two singularities.

Supergravity backgrounds of the η-deformed AdS2 × S2 × T6 and AdS5 × S5 superstrings
Journal of High Energy Physics, 2019 We construct supergravity backgrounds for the integrable η-deformations of the AdS2 × S2 × T6 and AdS5 × S5 superstring sigma models. The η-deformation is governed by an R-matrix that solves the non-split modified classical Yang-Baxter equation on the ...

Supersymmetric action for 6D (4, 0) supergravity
Journal of High Energy Physics, 2022 We give a linearized but otherwise complete supersymmetric action for N $$ \mathcal{N} $$ = (4, 0) supergravity in six dimensions, using a Kaluza-Klein-type 5 + 1 split of coordinates and fields.

From Minkowski to de Sitter in multifield no-scale models
Journal of High Energy Physics, 2019 We show the uniqueness of superpotentials leading to Minkowski vacua of single-field no-scale supergravity models, and the construction of dS/AdS solutions using pairs of these single-field Minkowski superpotentials.

N=2 central charge superspace and a minimal supergravity multiplet
, 1998 We extend the notion of central charge superspace to the case of local supersymmetry. Gauged central charge transformations are identified as diffeomorphisms on the same footing as spacetime diffeomorphisms and local supersymmetry transformations.

Superconformal vector multiplet self-couplings and generalised Fayet-Iliopoulos terms
Physics Letters B, 2019 As an extension of the recent construction of generalised Fayet-Iliopoulos terms in N=1 supergravity given in [1], we present self-interactions for a vector multiplet coupled to conformal supergravity.

Wrapped NS5-branes, consistent truncations and Inönü-Wigner contractions
Journal of High Energy Physics, 2021 We construct consistent Kaluza-Klein truncations of type IIA supergravity on (i) Σ2 × S 3 and (ii) Σ3 × S 3, where Σ2 = S 2 /Γ, ℝ2 /Γ, or ℍ2 /Γ, and Σ3 = S 3 /Γ, ℝ3 /Γ, or ℍ3 /Γ, with Γ a discrete group of symmetries, corresponding to NS5-branes wrapped ...
