Scattering amplitudes and Wilson loops in twistor space [PDF]
, 2011 This article reviews the recent progress in twistor approaches to Wilson loops, amplitudes and their duality for N=4 super Yang-Mills. Wilson loops and amplitudes are derived from first principles using the twistor action for maximally supersymmetric ...

Energy of sections of the Deligne–Hitchin twistor space [PDF]
, 2021 We study a natural functional on the space of holomorphic sections of the Deligne–Hitchin moduli space of a compact Riemann surface, generalizing the energy of equivariant harmonic maps corresponding to twistor lines.

A twistor space action for Yang-Mills theory [PDF]
, 2021 We consider the twistor space P6≅R4×CP1 of R4 with a nonintegrable almost complex structure J such that the canonical bundle of the almost complex manifold (P6,J) is trivial.

Twistor space origins of the Newman-Penrose map
SciPost 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 Interpretation of Harmonic Spheres and Yang–Mills Fields
Mathematics, 2015 We consider the twistor descriptions of harmonic maps of the Riemann sphere into Kähler manifolds and Yang–Mills fields on four-dimensional Euclidean space.

Twistor quadrics and black holes [PDF]
, 2023 A simple procedure is given to construct curved, non-self-dual (complexified)Kaehler metrics on space-time in terms of deformations of holomorphic quadricsurfaces in flat twistor space.

4D higher spin black holes with nonlinear scalar fluctuations
Journal of High Energy Physics, 2017 We construct an infinite-dimensional space of solutions to Vasiliev’s equations in four dimensions that are asymptotic to AdS spacetime and superpose massless scalar particle modes over static higher spin black holes. Each solution is obtained by a large

Proceedings of the London Mathematical Society, 1981 The work of R. Penrose has shown the deep relationship between the conformal structure of Minkowski space and the complex geometry of lines in projective three-space. This transformation applies to a more general class of conformal structures and in particular there is a riemannian version, described in [5], which is itself of interest to mathematical ...

Toward a twistor action for chiral higher-spin gravity [PDF]
, 2023 A covariant twistor action for chiral higher-spin theory in (A)dS and flat space is constructed in terms of a holomorphic Chern-Simons theory on twistor space. The action reproduces all known cubic vertices of chiral higher-spin theory in flat space. The

Two-Twistor Space, Commuting Composite Minkowski Coordinates and Particle Dynamics
, 2005 We employ the modification of the basic Penrose formula in twistor theory, which allows to introduce commuting composite space-time coordinates. It appears that in the course of such modification the internal symmetry SU(2) of two-twistor system is ...
