Properties of enhançons in supergravity [PDF]
, 2003 A certain class of naked singularities, related to N = 2 pure super Yang-Mills theory, are resolved in string theory with the enhançon mechanism. We study the properties of the enhançon in supergravity.

Extended JT supergravity and random matrix models: The power of the string equation
Journal of High Energy PhysicsA number of supersymmetric Jackiw-Teitelboim (JT) gravity theories are known to be described (in the Euclidean path integral formulation) by double-scaled random matrix models. Such matrix models can be characterized using a certain “string equation”. It

Superconformal vector multiplet self-couplings and generalised Fayet-Iliopoulos terms
Physics Letters B, 2019 As an extension of the recent construction of generalised Fayet-Iliopoulos terms in N=1 supergravity given in [1], we present self-interactions for a vector multiplet coupled to conformal supergravity.

Space biomedicine‐oriented bioink and biomimetic blood‒brain barrier
VIEW, Volume 7, Issue 3, June 2026.Bioinks and bioprinting play a pivotal role in the successful delivery of cell models and the fabrication of tissue models for space biomedicine research. This study investigated the effects of hypergravity and vibration on two‐dimensional adherent cells and three‐dimensional embedded cells and provided methods for storing hybrid bioink and high ...

Jordan frame in supergravity and cosmology
Journal of High Energy PhysicsThe superconformal action can be gauge-fixed in a gauge where it leads to the Einstein frame supergravity defined by a Kähler potential K z z ¯ $$ \mathcal{K}\left(z,\overline{z}\right) $$ , or in a gauge where it leads to a Jordan frame supergravity ...

Wrapped NS5-branes, consistent truncations and Inönü-Wigner contractions
Journal of High Energy Physics, 2021 We construct consistent Kaluza-Klein truncations of type IIA supergravity on (i) Σ2 × S 3 and (ii) Σ3 × S 3, where Σ2 = S 2 /Γ, ℝ2 /Γ, or ℍ2 /Γ, and Σ3 = S 3 /Γ, ℝ3 /Γ, or ℍ3 /Γ, with Γ a discrete group of symmetries, corresponding to NS5-branes wrapped ...

Radiative corrections in supergravity models of inflation
Journal of High Energy PhysicsSupergravity provides the natural supersymmetric framework for early universe cosmology. A broad class of inflationary models in no-scale supergravity yields tree-level predictions for cosmic microwave background (CMB) observables that closely resemble ...

SUSY breaking after inflation in supergravity with inflaton in a massive vector supermultiplet
Physics Letters B, 2016 We propose a limited class of models, describing interacting chiral multiplets with a non-minimal coupling to a vector multiplet, in curved superspace of N=1 supergravity. Those models are suitable for the inflationary model building in supergravity with

Batteries &Supercaps, Volume 9, Issue 5, May 2026.Lithium‐ion batteries used in space applications are exposed to extreme conditions, including radiation, vacuum, wide temperature fluctuations, and long storage times, all of which accelerate degradation. This review article summarizes the main degradation mechanisms affecting battery performance in space environments, including capacity fade ...
