Supertwistor realisations of AdS superspaces

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We propose supertwistor realisations of (p, q) anti-de Sitter (AdS) superspaces in three dimensions and $${\mathcal {N}}$$ N -extended AdS superspaces in four dimensions.

Computational Modeling of Reticular Materials: The Past, the Present, and the Future

open access: yesAdvanced Materials, EarlyView.
Reticular materials are advanced materials with applications in emerging technologies. A thorough understanding of material properties at operating conditions is critical to accelerate the deployment at an industrial scale. Herein, the status of computational modeling of reticular materials is reviewed, supplemented with topical examples highlighting ...

On five-dimensional superspaces [PDF]

open access: yesJournal of High Energy Physics, 2006
Recent one-loop calculations of certain supergravity-mediated quantum corrections in supersymmetric brane-world models employ either the component formulation (hep-th/0305184) or the superfield formalism with only half of the bulk supersymmetry manifestly realized (hep-th/0305169 and hep-th/0411216).

N = 1 supercurrents of eleven-dimensional supergravity

open access: yesJournal of High Energy Physics, 2018
Eleven-dimensional supergravity can be formulated in superspaces locally of the form X × Y where X is 4D N = 1 conformal superspace and Y is an arbitrary 7-manifold admitting a G 2-structure.

Superforms in six-dimensional superspace

open access: yes, 2016
A bstractWe investigate the complex of differential forms in curved, six-dimensional, N = (1,0) superspace. The superconformal group acts on this complex by super-Weyl transformations.

Relational Supersymmetry via the Dressing Field Method and Matter‐Interaction Supergeometric Framework

open access: yesAnnalen der Physik, EarlyView.
Applications of the Dressing Field Method are reviewed and further expanded to the very foundations of the supersymmetric framework, where it allows to build relational supersymmetric field theory. Furthermore, a novel approach is proposed giving a unified description of fermionic matter fields and bosonic gauge fields: a Matter‐Interaction ...

Equivalence of superspace groups [PDF]

open access: yesActa Crystallographica Section A Foundations of Crystallography, 2012
An algorithm is presented which determines the equivalence of two settings of a (3 + d)-dimensional superspace group (d = 1, 2, 3). The algorithm has been implemented as a web tool findssg on SSG(3+d)D, providing the transformation of any user-given superspace group to the standard setting of this superspace group in SSG(3+d)D.

On conformal supergravity and harmonic superspace [PDF]

open access: yes, 2015
A bstractThis paper describes a fully covariant approach to harmonic superspace. It is based on the conformal superspace description of conformal supergravity and involves extending the supermanifold ℳ$$ \mathrm{\mathcal{M}} $$4|8 by the tangent bundle ...

Projective superspaces in practice [PDF]

open access: yesJournal of Geometry and Physics, 2018
We study the supergeometry of complex projective superspaces $\mathbb{P}^{n|m}$. First, we provide formulas for the cohomology of invertible sheaves of the form $\mathcal{O}_{\mathbb{P}^{n|m}} (\ell)$, that are pull-back of ordinary invertible sheaves on the reduced variety $\mathbb{P}^n$.

Towards massive field-theory amplitudes from the cohomology of pure spinor superspace

open access: yesJournal of High Energy Physics
By analogy with the formula for the massless string disk amplitudes, we define massive field-theory tree amplitudes and conjecture that the BRST cohomology structure of pure spinor superspace fixes their form. We give evidence by deriving the pure spinor
