Holographic RG flows and $$AdS_5$$ AdS5 black strings from 5D half-maximal gauged supergravity
We study five-dimensional $$N=4$$ N=4 gauged supergravity coupled to five vector multiplets with compact and non-compact gauge groups $$U(1)\times SU(2)\times SU(2)$$ U(1)×SU(2)×SU(2) and $$U(1)\times SO(3,1)$$ U(1)×SO(3,1) . For $$U(1)\times SU(2)\times

That supergravity can refine grains is verified in many materials. However, the underlying mechanism is still an open question. Although some convincing theories have been proposed, including the ‘crystal rain’ theory and the dendrite fragmentation ...

Minimal Constrained Supergravity [PDF]
We describe minimal supergravity models where supersymmetry is non-linearly realized via constrained superfields. We show that the resulting actions differ from the so called "de Sitter" supergravities because we consider constraints eliminating directly the auxiliary fields of the gravity multiplet.

Magnetic charges in supergravity
Abstract In this paper we study the dual charges of $$ \mathcal{N} $$ N = 1 supergravity in asymptotically flat space-time. The action considered is the usual supergravity action with a topological contribution.

Structure of linearized supergravity and conformal supergravity [PDF]
Abstract We give, at the linearized level, the supersymmetric generalization of various tensors of differential geometry, such as the metric tensor and the Riemann, Einstein and Weyl tensors. Using them we write the Lagrangian and the equations of motion of linearized supergravity and conformal supergravity with coupling to sources. Both theories are

Octonionic Magical Supergravity, Niemeier Lattices, and Exceptional & Hilbert Modular Forms
Abstract The quantum degeneracies of Bogomolny‐Prasad‐Sommerfield (BPS) black holes of octonionic magical supergravity in five dimensions are studied. Quantum degeneracy is defined purely number theoretically as the number of distinct states in charge space with a given set of invariant labels.

On the Starobinsky Model of Inflation from Supergravity
We discuss how the higher-derivative Starobinsky model of inflation originates from N=1 supergravity. It is known that, in the old-minimal supergravity description written by employing a chiral compensator in the superconformal framework, the Starobinsky

Supersymmetric $$AdS_5$$ AdS5 black holes and strings from 5D $$N=4$$ N=4 gauged supergravity
We study supersymmetric $$AdS_3\times \Sigma _2$$ AdS3×Σ2 and $$AdS_2\times \Sigma _3$$ AdS2×Σ3 solutions, with $$\Sigma _2=S^2,H^2$$ Σ2=S2,H2 and $$\Sigma _3=S^3,H^3$$ Σ3=S3,H3 , in five-dimensional $$N=4$$ N=4 gauged supergravity coupled to five vector

Evolutionary Algorithms for Multi‐Center Solutions
Abstract Large classes of multi‐center supergravity solutions have been constructed in the study of supersymmetric black holes and their microstates. Many smooth multi‐center solutions have the same charges as supersymmetric black holes, with all centers deep inside a long black‐hole‐like throat.
