Twisted compactifications and conformal defects from ISO(3) $$\times $$ × U(1) F(4) gauged supergravity

open access: yesEuropean Physical Journal C: Particles and Fields
We study holographic solutions describing RG flows across dimensions from five-dimensional $$N=2$$ N = 2 SCFT to SCFTs in three and two dimensions using matter-coupled F(4) gauged supergravity with $$ISO(3)\times U(1)$$ I S O ( 3 ) × U ( 1 ) gauge group.

Toward Supergravity Spectral Action

open access: yes, 2013
A spectral action of Euclidean supergravity is proposed. We calculate up to $a_4$, the Seeley-Dewitt coefficients in the expansion of the spectral action associated to the supergravity Dirac operator.

Scanning of the supersymmetry breaking scale and the gravitino mass in supergravity [PDF]

open access: yes, 2016
A bstractWe consider the minimal three-form N$$ \mathcal{N} $$ = 1 supergravity coupled to nilpotent three-form chiral superfields. The supersymmetry breaking is sourced by the three-forms of the chiral multiplets, while the value of the gravitino mass ...

de Sitter State in Heterotic String Theory

open access: yesFortschritte der Physik, Volume 72, Issue 11, November 2024.
Abstract Recent no‐go theorems have ruled out four‐dimensional classical de Sitter vacua in heterotic string theory. On the other hand, the absence of a well‐defined Wilsonian effective action and other related phenomena also appear to rule out such time‐dependent vacua with de Sitter isometries, even in the presence of quantum corrections.

Supergravity Theories in $D\ge 12$ Coupled to Super p-Branes

open access: yes, 1998
We construct supergravity theories in twelve and thirteen dimensions with the respective signatures (10,2) and (11,2) with some technical details. Starting with N=1 supergravity in 10+2 dimensions coupled to Green-Schwarz superstring, we give N=2 chiral ...

Recent and new results on octonionic Bergman and Szegö kernels

open access: yesMathematical Methods in the Applied Sciences, Volume 47, Issue 10, Page 7888-7901, 15 July 2024.
Very recently one has started to study Bergman and Szegö kernels in the setting of octonionic monogenic functions. In particular, explicit formulas for the Bergman kernel for the octonionic unit ball and for the octonionic right half‐space as well as a formula for the Szegö kernel for the octonionic unit ball have been established.

Recycling of iron and steel slag for carbon reduction and low‐environment load application

open access: yesCarbon Neutralization, Volume 3, Issue 4, Page 606-628, July 2024.
This article reviews the coupling of the research progress of blast furnace slag and steel slag in glass‐ceramics, ceramic products, mineral wool, and cementitious in recent years. The research status of CO2 fixation by iron and steel slag was discussed.

Vector Meson Spectrum from Top-Down Holographic QCD

open access: yesAxioms
We elaborate on the brane configuration that gives rise to a QCD-like gauge theory that confines at low energies and becomes scale invariant at the highest energies.

The embedding tensor of Scherk-Schwarz flux compactifications from eleven dimensions

open access: yes, 2013
We study the Scherk-Schwarz reduction of D=11 supergravity with background fluxes in the context of a recently developed framework pertaining to D=11 supergravity.

Minimal supergravity inflation

open access: yesPhysical Review D, 2016
We construct inflationary models in the context of supergravity with orthogonal nilpotent superfields [1]. When local supersymmetry is gauge-fixed in the unitary gauge, these models describe theories with only a single real scalar (the inflaton), a ...
