Modeling General Asymptotic Calabi–Yau Periods

open access: yesFortschritte der Physik, Volume 73, Issue 7, July 2025.
Abstract In the quest to uncovering the fundamental structures that underlie some of the asymptotic Swampland conjectures the authors initiate the general study of asymptotic period vectors of Calabi–Yau manifolds. The strategy is to exploit the constraints imposed by completeness, symmetry, and positivity, which are formalized in asymptotic Hodge ...

Sen's mechanism for self-dual super Maxwell theory

open access: yesNuclear Physics B
In several elementary particle scenarios, self-dual fields emerge as fundamental degrees of freedom. Some examples are the D=2 chiral boson, D=10 Type IIB supergravity, and D=6 chiral tensor multiplet theory.

Electrodeposited Manganese Dioxides and Their Composites as Electrocatalysts for Energy Conversion Reactions

open access: yesChemSusChem, Volume 18, Issue 5, March 3, 2025.
This review focuses on the electrochemical synthesis of MnO2 materials and their composites and their application as electrocatalysts for OER and HER reactions for the conversion of renewable energy into chemical fuels. The electrocatalytic function of electrodeposited MnO2 for ORR and bifunctional ORR/OER for efficient operation of fuel cells and ...

The two-loop five-particle amplitude in N $$ \mathcal{N} $$ = 8 supergravity

open access: yesJournal of High Energy Physics, 2019
We compute for the first time the two-loop five-particle amplitude in N $$ \mathcal{N} $$ = 8 supergravity. Starting from the known integrand, we perform an integration-by-parts reduction and express the answer in terms of uniform weight master integrals.

Flux quantization on 11-dimensional superspace

open access: yesJournal of High Energy Physics
Flux quantization of the C-field in 11d supergravity is arguably necessary for the (UV-)completion of the theory, in that it determines the torsion charges carried by small numbers N ≪ ∞ of M-branes.

Aspects of supersymmetry breaking driven inflation in orbifold models

open access: yesEuropean Physical Journal C: Particles and Fields
We consider gravitationally induced corrections to inflaton potentials driven by supersymmetry breaking in a five-dimensional supergravity, compactified on a $$ S_1/Z_2 $$ S 1 / Z 2 orbifold. The supersymmetry breaking takes place on the hidden brane and

Massive vector multiplet with Dirac-Born-Infeld and new Fayet-Iliopoulos terms in supergravity

open access: yesJournal of High Energy Physics, 2018
We propose a four-dimensional N = 1 supergravity-based Starobinsky-type inflationary model in terms of a single massive vector multiplet, whose action includes the Dirac-Born-Infeld-type kinetic terms and a generalized (new) Fayet-Iliopoulos-type term ...

SU(2) × SU(2) dilaton Weyl multiplets for maximal conformal supergravity in four, five, and six dimensions

open access: yesJournal of High Energy Physics
New dilaton Weyl multiplets are constructed in four and five space-time dimensions for N = 4 and N = 2 conformal supergravity respectively. They are constructed from a mixture of the old dilaton weyl multiplets with an on-shell vector multiplet.
