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.

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 ...

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.

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.

$$ \mathcal{N} $$ = (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.

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.

Gravitational Topological Quantum Field Theory Versus N = 2 D = 8 Supergravity and its lift to N = 1 D = 11 Supergravity [PDF]
, 2003 In a previous work, it was shown that the 8-dimensional topological quantum field theory for a metric and a Kalb-Ramond 2-form gauge field determines N = 1 D = 8 supergravity.
