From Minkowski to de Sitter in multifield no-scale models
Journal of High Energy Physics, 2019 We show the uniqueness of superpotentials leading to Minkowski vacua of single-field no-scale supergravity models, and the construction of dS/AdS solutions using pairs of these single-field Minkowski superpotentials.

Tree level supergravity and the Matrix model [PDF]
Nuclear Physics B, 2000 It has recently been shown that the Matrix model and supergravity give the same predictions for three graviton scattering. This contradicts an earlier claim in the literature (hep-th/9710174). We explain the error in this earlier work, and go on to show that certain terms in the $n$-graviton scattering amplitude involving $v^{2n}$ are given correctly ...

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 ...

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.

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 ...

Enriques and octonionic magic supergravity models [PDF]
Journal of High Energy Physics, 2008 We reconsider the Enriques Calabi Yau (FHSV) model and its string derivation and argue that the Octonionic magic supergravity theory admits a string interpretation closely related to the Enriques model. The uplift to D=6 of the Octonionic magic model has 16 abelian vectors related to the rank of Type I and Heterotic strings.

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

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 ...
