Non-Abelian Tensor Multiplet Equations from Twistor Space

open access: yesCommunications in Mathematical Physics, 2014
We establish a Penrose-Ward transform yielding a bijection between holomorphic principal 2-bundles over a twistor space and non-Abelian self-dual tensor fields on six-dimensional flat space-time.

Twistor space origins of the Newman-Penrose map

open access: yesSciPost Physics, 2022
Recently, we introduced the "Newman-Penrose map", a novel correspondence between a certain class of solutions of Einstein's equations and self-dual solutions of the vacuum Maxwell equations, which we showed was closely related to the classical double ...

Twistor surfaces and right-flat spaces

open access: yesGeneral Relativity and Gravitation, 1978
The connection between the deformed twistor space of Penrose and Plebanski's form for the general right-flat metric is explored. A Hamiltonian formalism for obtaining the twistor surfaces in a right-flat space with Plebanski's Ω-function as Hamiltonian is obtained.

Ambitwistor strings in six and five dimensions

open access: yesJournal of High Energy Physics, 2021
Ambitwistor strings are chiral (holomorphic) strings whose target is the space of complex null geodesics, ambitwistor space. We introduce twistor representations of ambitwistor space in 6 and 5 dimensions.

Generalized almost even-Clifford manifolds and their twistor spaces

open access: yesComplex Manifolds, 2021
Motivated by the recent interest in even-Clifford structures and in generalized complex and quaternionic geometries, we introduce the notion of generalized almost even-Clifford structure. We generalize the Arizmendi-Hadfield twistor space construction on

Twistor Actions for Integrable Systems

open access: yesJournal of High Energy Physics, 2021
Many integrable systems can be reformulated as holomorphic vector bundles on twistor space. This is a powerful organizing principle in the theory of integrable systems.

Unobstructedness of hyperkähler twistor spaces [PDF]

open access: yesMathematische Zeitschrift, 2021
AbstractA family of irreducible holomorphic symplectic (ihs) manifolds over the complex projective line has unobstructed deformations if its period map is an embedding. This applies in particular to twistor spaces of ihs manifolds. Moreover, a family of ihs manifolds over a subspace of the period domain extends to a universal family over an open ...

Mini-twistors and the Cotton double copy

open access: yesJournal of High Energy Physics, 2023
The double copy relates quantities in gauge, gravity and related theories. A well-known procedure for relating exact classical solutions is the Weyl double copy in four spacetime dimensions, and a three-dimensional analogue of this — the Cotton double ...
