String and M-theory contain a family of branes forming U -duality multiplets. In particular, standard branes with codimension higher than or equal to two, can be explicitly found as supergravity solutions.

Scattering amplitudes in N=2 Maxwell-Einstein and Yang-Mills/Einstein supergravity [PDF]
We expose a double-copy structure in the scattering amplitudes of the generic Jordan family of N=2 Maxwell-Einstein and Yang-Mills/Einstein supergravity theories in four and five dimensions.

Abstract The unification of conformal and fuzzy gravities with internal interactions is based on the facts that i) the tangent group of a curved manifold and the manifold itself do not necessarily have the same dimensions and ii) both gravitational theories considered here have been formulated in a gauge theoretic way.

The supergravity and in‐situ evaporation are utilized to produce GO thin films with a record‐high mechanical strength of 540 MPa. The supergravity confines the 2D flakes within a very thin layer and creates a large all‐directional shear stress to induce the superalignment, while in‐situ evaporation accelerates the dehydration and facilitates the ester ...

Global properties of the conformal manifold for S-fold backgrounds
We study a one-parameter family of N $$ \mathcal{N} $$ = 2 anti-de Sitter vacua with U(1)2 symmetry of gauged four-dimensional maximal supergravity, with dyonic gauge group [SO(6) × SO(1, 1)] ⋉ ℝ12. These backgrounds are known to correspond to Type IIB S-

Supersymmetric AdS Solitons, Ground States, and Phase Transitions in Maximal Gauged Supergravity
We review some recent soliton solutions in a class of four-dimensional supergravity theories. The latter can be obtained from black hole solutions by means of a double Wick rotation.

Instability of supersymmetric black holes via quantum phase transitions
In this paper we prove that the four-dimensional hyperbolic supersymmetric black holes can be unstable in the canonical ensemble. To this end, we work with an infinite class of N $$ \mathcal{N} $$ = 2 supergravity theories interpolating between all the ...

Inverse dualisation and non-local dualities between Einstein gravity and supergravities [PDF]
We investigate non-local dualities between suitably compactified higher-dimensional Einstein gravity and supergravities which can be revealed if one reinterprets the dualised Kaluza-Klein two-forms in $D>4$ as antisymmetric forms belonging to ...

Double Copy From Tensor Products of Metric BV■‐Algebras
Abstract Field theories with kinematic Lie algebras, such as field theories featuring color–kinematics duality, possess an underlying algebraic structure known as BV■‐algebra. If, additionally, matter fields are present, this structure is supplemented by a module for the BV■‐algebra.

The inheritance of energy conditions: Revisiting no-go theorems in string compactifications
One of the fundamental challenges in string theory is to derive realistic four-dimensional cosmological backgrounds from it despite strict consistency conditions that constrain its possible low-energy backgrounds.
