Holographic RG flows and $$AdS_5$$ AdS5 black strings from 5D half-maximal gauged supergravity

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
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

Supersymmetric M-brane Solution in a Dynamical Background

open access: yesGalaxies, 2018
Supersymmetry arises in certain theories of fermions coupled to gauge fields and gravity in a spacetime of 11 dimensions. The dynamical brane background has mainly been studied for the class of purely bosonic solutions only, but recent developments ...

Fortuity and supergravity

open access: yesJournal of High Energy Physics
A bstract BPS states in holographic CFTs naturally split into those describing black holes in the bulk and those that do not, with black hole states only existing above a certain energy threshold. In the context of the AdS 3

Inflation, supergravity, and superstrings [PDF]

open access: yesPhysical Review D, 1995
The positive potential energy required for inflation spontaneously breaks supersymmetry and in general gives any would-be inflaton an effective mass of order the inflationary Hubble parameter thus ruling it out as an inflaton. In this paper I give simple conditions on the superpotential that eliminate some potential sources for this mass, and derive a ...

Higher Curvature Supergravity and Cosmology

open access: yes, 2015
In this contribution we describe dual higher-derivative formulations of some cosmological models based on supergravity. Work in this direction started with the Starobinsky model, whose supersymmetric extension was derived in the late 80's and was ...

Quantum No-Scale Regimes and String Moduli

open access: yesUniverse, 2018
We review that in no-scale models in perturbative string theory, flat, homogeneous and isotropic cosmological evolutions found at the quantum level can enter into “quantum no-scale regimes„ (QNSRs).

The dynamic recrystallization of the Ni-based superalloy under the supergravity stress and high temperature

open access: yesMaterials Research Letters
The occurrence of recrystallization will greatly decrease the service life of superalloy blades. The dynamic recrystallization of a Ni-based single crystal superalloy under supergravity stress and high temperature was studied. When tested at 950 °C, only
