Aspects of twistors and tractors in field theory
… functions. In the final chapter, we construct a minitwistor action for Yang--Mills--Higgs theory in three dimensions. The Feynman diagrams of this action will construct perturbation theory around solutions of the Bogomolny equations in much the same way that MHV diagrams describe perturbation …

Twistor Space and Celestial Holography
… 5 dimensional hyperbolic space. We discuss the minitwistor space of the bulk and its relation to the ambitwistor space of the boundary. The third part of my thesis is a paper on spectral flow and localisation in AdS$_3$ string theory. The fourth and final part of my thesis is a discussion of …

Integrability from Chern-Simons theories
… to obtain a 5d Chern-Simons theory on minitwistor correspondence space describing the Bogomolny equations.

AdS3 Holography from the Worldsheet
… be naturally understood as a sigma model on the minitwistor space of $AdS_3$. The incidence relations are studied, showing how they encode both bulk and boundary physics simultaneously. The sigma model we present has several important differences with conventional twistor string constructions, …
