Warm dark energy

Gianguido Dall'Agata, Sergio Gonzalez-Martin, Alexandros Papageorgiou +1

Motivated by some of the recent swampland conjectures, we study the implementation for the late time acceleration of the Universe of a mechanism developed by Anber and Sorbo in the…

$T T ˉ$ deformations and integrable spin chains

Enrico Marchetto, Alessandro Sfondrini, Zhou Yang

We consider current-current deformations that generalise $T T ˉ$ ones, and show that they may be also introduced for integrable spin chains. In analogy with the integrable QFT s…

Flow equations for generalised $T T ˉ$ deformations

Guzmán Hernández-Chifflet, Stefano Negro, Alessandro Sfondrini

We consider the most general set of integrable deformations extending the $T T ˉ$ deformation of two-dimensional relativistic QFTs. They are CDD deformations of the theory's fac…

Self-interacting chiral p-forms in higher dimensions

Ginevra Buratti, Kurt Lechner, Luca Melotti

There exists no natural variational principle for the dynamics of abelian p-form potentials with self-dual field strengths, also called chiral p-forms. Relying on the PST method, w…

$T T ˉ$ deformations as TsT transformations

Alessandro Sfondrini, Stijn J. van Tongeren

The relationship between $T T ˉ$ deformations and the uniform light-cone gauge, first noted in arXiv:1804.01998, provides a powerful generating technique for deformed models. We…

How many fluxes fit in an EFT?

Stefano Lanza, Fernando Marchesano, Luca Martucci +1

We extend the recent construction of 4d $N = 1$ three-form Lagrangians by including the most general three-form multiplets necessary to reproduce any F-term potential in st…

Vector Space of Feynman Integrals and Multivariate Intersection Numbers

Hjalte Frellesvig, Federico Gasparotto, Manoj K. Mandal +3

Feynman integrals obey linear relations governed by intersection numbers, which act as scalar products between vector spaces. We present a general algorithm for constructing multiv…

Systematics of consistent truncations from generalised geometry

Davide Cassani, Gregoire Josse, Michela Petrini +1

We present a generalised geometry framework for systematically constructing consistent truncations of ten- and eleven-dimensional supergravity preserving varying fractions of super…

Orbits in Non-Supersymmetric Magic Theories

Alessio Marrani, Luca Romano

We determine and classify the electric-magnetic duality orbits of fluxes supporting asymptotically flat, extremal black branes in $D = 4, 5, 6$ space-time dimensions in the so-called n…

Exceptional Super Yang-Mills in $D = 27 + 3$ and Worldvolume M-Theory

Michael Rios, Alessio Marrani, David Chester

Bars and Sezgin have proposed a super Yang-Mills theory in $D = s + t = 11 + 3$ space-time dimensions with an electric 3-brane that generalizes the 2-brane of M-theory. More recently, the…

The BPS limit of rotating AdS black hole thermodynamics

Davide Cassani, Lorenzo Papini

We consider rotating, electrically charged, supersymmetric AdS black holes in four, five, six and seven dimensions, and provide a derivation of the respective extremization princip…

Duality invariant self-interactions of abelian p-forms in arbitrary dimensions

Ginevra Buratti, Kurt Lechner, Luca Melotti

We analyze non-linear interactions of 2N-form Maxwell fields in a space-time of dimension D=4N. Based on the Pasti-Sorokin-Tonin (PST) method, we derive the general consistency con…

Holographic correlators in AdS $_{3}$ without Witten diagrams

Stefano Giusto, Rodolfo Russo, Alexander Tyukov +1

We present a formula for the holographic 4-point correlators in AdS $_{3} \times S^{3}$ involving four single-trace operators of dimension $k, k, l, l$ . As an input we use the supergrav…

Supermembranes and domain walls in $N = 1$ , $D = 4$ SYM

Igor Bandos, Stefano Lanza, Dmitri Sorokin

We construct a manifestly supersymmetric and kappa-symmetry invariant worldvolume action describing the coupling of a dynamical membrane to an $N = 1$ , $D = 4$ $S U (N)$ super-Y…

Black holes and general Freudenthal transformations

L. Borsten, M. J. Duff, J. J. Fernández-Melgarejo +2

We study General Freudenthal Transformations (GFT) on black hole solutions in Einstein-Maxwell-Scalar (super)gravity theories with global symmetry of type $E_{7}$ . GFT can be conside…

AdS $_{3}$ Holography at Dimension Two

Stefano Giusto, Sami Rawash, David Turton

Holography can provide a microscopic interpretation of a gravitational solution as corresponding to a particular CFT state: the asymptotic expansion in gravity encodes the expectat…

The asymptotic growth of states of the 4d N=1 superconformal index

Alejandro Cabo-Bizet, Davide Cassani, Dario Martelli +1

We show that the superconformal index of N=1 superconformal field theories in four dimensions has an asymptotic growth of states which is exponential in the charges. Our analysis h…

We compute four-point functions in the Heavy-Heavy-Light-Light limit involving all possible $\frac{1}{8}$ -BPS heavy states whose dual supergravity solutions are explicitly known, a…

Higher Forms and Membranes in 4D Supergravities

I. Bandos, F. Farakos, S. Lanza +2

We review the dynamical generation of coupling constants in 4D supergravity by means of gauge three-form fields. The latter are introduced as components of particular chiral superm…
