On the equivalence of Starobinsky and Higgs inflationary models in gravity and supergravity [PDF]
Journal of Physics A: Mathematical and Theoretical, 2019 Starobinsky inflation and Higgs inflation in gravity, and their equivalence based on the common inflationary potential are extended to supergravity in the proper framework, where the Starobinsky and Higgs descriptions of inflation arise in two different ...

Holographic microstate counting for AdS4 black holes in massive IIA supergravity [PDF]
Journal of High Energy Physics, 2017 We derive the Bekenstein-Hawking entropy for a class of BPS black holes in the massive type IIA supergravity background AdS4 × S6 from a microscopic counting of supersymmetric ground states in a holographically dual field theory.

New Black Hole Solutions in
Universe, 2021 We review a special class of N=2 supergravity model that interpolates all the single-dilaton truncations of the maximal SO(8) gauged supergravity.

Renormalization Group Flows from Five-Dimensional Supergravity [PDF]
, 1999 The use of gauged ${\cal N} = 8$ supergravity as a tool in studying the AdS/CFT correspondence for ${\cal N} = 4$ Yang-Mills theory is reviewed. The supergravity potential implies a non-trivial, supersymmetric IR fixed point, and the flow to this fixed ...

Supersymmetric AdS$$_2\times \Sigma _2$$ 2×Σ2 solutions from tri-sasakian truncation
European Physical Journal C: Particles and Fields, 2017 A class of $$\mathrm{AdS}_2\times \Sigma _2$$ AdS2×Σ2 , with $$\Sigma _2$$ Σ2 being a two-sphere or a hyperbolic space, solutions within four-dimensional $$N=4$$ N=4 gauged supergravity coupled to three-vector multiplets with dyonic gauging is identified.

On the Vacuum Structure of the
Universe, 2021 We consider N=4 conformal supergravity with an arbitrary holomorphic function of the complex scalar S which parametrizes the SU(1,1)/U(1) coset. Assuming non-vanishings vevs for S and the scalars in a symmetric matrix Eij of the 10¯ of SU(4) R-symmetry ...

, 2006 We adapt the spinorial geometry method to investigate supergravity backgrounds with near maximal number of supersymmetries. We then apply the formalism to show that the IIB supergravity backgrounds with 31 supersymmetries preserve an additional ...

Warped AdS6 × S2 in Type IIB supergravity II: global solutions and five-brane webs [PDF]
, 2017 A bstractMotivated by the construction of holographic duals to five-dimensional superconformal quantum field theories, we obtain global solutions to Type IIB supergravity invariant under the superalgebra F (4) on a space-time of the form AdS6 × S2 warped

Supergravity backgrounds of the η-deformed AdS2 × S2 × T6 and AdS5 × S5 superstrings [PDF]
Journal of High Energy Physics, 2018 We construct supergravity backgrounds for the integrable η-deformations of the AdS2 × S2 × T6 and AdS5 × S5 superstring sigma models. The η-deformation is governed by an R-matrix that solves the non-split modified classical Yang-Baxter equation on the ...

Supergravity metallurgy: principles, experimental methods, techniques, and applications
工程科学学报, 2021 Supergravity significantly increases the gravity difference between two phases and thus can accelerate phase separation in solid–liquid mixtures, liquid–liquid mixtures, and liquid–bubble mixtures that have high temperatures and viscosities.
