Corrections to AdS5 black hole thermodynamics from higher-derivative supergravity [PDF]

Journal of High Energy Physics, 2022
We study four-derivative corrections to five-dimensional minimal gauged supergravity. We evaluate the on-shell action of the AdS5 black hole solution with two independent angular momenta and one electric charge at linear order in the corrections.

Kaluza-Klein spectrometry for ${\rm AdS_{3}}$ vacua

SciPost Physics, 2021
We use exceptional field theory to compute Kaluza-Klein mass spectra around ${\rm AdS_{3}}$ vacua that sit in half-maximal gauged supergravity in three dimensions.

A Systematic Approach to Consistent Truncations of Supergravity Theories

Universe, 2021
Exceptional generalised geometry is a reformulation of eleven/ten-dimensional supergravity that unifies ordinary diffeomorphisms and gauge transformations of the higher-rank potentials of the theory in an extended notion of diffeormorphisms.

Polyvector deformations in eleven-dimensional supergravity [PDF]

Physical Review D, 2020
We consider 3- and 6-vector deformations of 11-dimensional supergravity backgrounds of the form $M_5\times M_6$ admitting at least 3 Killing vectors. Using flux formulation of the E${}_{6(6)}$ exceptional field theory we derive (sufficient) conditions ...

Tachyonic Kaluza-Klein modes and the AdS swampland conjecture

Journal of High Energy Physics, 2020
We compute the Kaluza-Klein spectrum of the non-supersymmetric SO(3) × SO(3)-invariant AdS4 vacuum of 11-dimensional supergravity, whose lowest-lying Kaluza-Klein modes belong to a consistent truncation to 4-dimensional N $$ \mathcal{N} $$ = 8 ...

4D N $$ \mathcal{N} $$ = 1 Kaluza-Klein superspace

Journal of High Energy Physics, 2020
Motivated by recent efforts to encode 11D supergravity in 4D N $$ \mathcal{N} $$ = 1 superfields, we introduce a general covariant framework relevant for describing any higher dimensional supergravity theory in external 4D N $$ \mathcal{N} $$ = 1 ...

Black hole chemistry, the cosmological constant and the embedding tensor

Journal of High Energy Physics, 2022
We study black-hole thermodynamics in theories that contain dimensionful constants such as the cosmological constant or coupling constants in Wald’s formalism.

Kaluza–Klein reduction on a maximally non-Riemannian space is moduli-free

Physics Letters B, 2019
We propose a novel Kaluza–Klein scheme which assumes the internal space to be maximally non-Riemannian, meaning that no Riemannian metric can be defined for any subspace.

$$ \mathcal{N} $$ = (8, 0) AdS vacua of three-dimensional supergravity [PDF]

Journal of High Energy Physics, 2019
We give a classification of fully supersymmetric chiral $$ \mathcal{N} $$ N = (8, 0) AdS3 vacua in general three-dimensional half-maximal gauged supergravities coupled to matter.

Janus and Hades in M-theory

Journal of High Energy Physics, 2022
Multi-parametric and analytic families of four-dimensional AdS3 × ℝ (Janus) and AdS3 × ℝ+ (Hades) solutions are constructed in the SO(8) gauged supergravity that arises from the consistent reduction of eleven-dimensional supergravity on S7 .
