Consistent truncations in higher derivative supergravity [PDF]
Journal of High Energy Physics, 2023 We consider the torus reduction of heterotic supergravity in the presence of four-derivative corrections. In particular, the reduction on Tn generically leads to a half-maximal supergravity coupled to n vector multiplets, and we show that it is ...

Cubic and higher-order supergravity couplings for AdS vacua using Exceptional Field Theory [PDF]
Journal of High Energy Physics, 2023 We show how to use Exceptional Field Theory to efficiently compute n-point couplings of all Kaluza-Klein modes for vacua that can be uplifted from maximal gauged supergravities to 10/11 dimensions via a consistent truncation.

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.

Journal of High Energy Physics, 2022 Supergravity brane solutions allow for a generalised type of Kaluza-Klein reduction onto brane worldvolumes. The known replacement of a flat worldvolume metric by a Ricci-flat metric constitutes a consistent Kaluza-Klein truncation of the starting higher-

, 2016 Dans cette thèse, nous présentons des constructions explicites de la correspondance AdS/CFT dans le contexte de la théorie des cordes de type II. Ces constructions sont visées à mieux comprendre aspects de la physique nonperturbative de théories des champs superconformes à d = 6,5,4 dimensions.

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 ...
