© 2016, The Author(s). Abstract: After a brief overview of the operator formalism for conventional string theory, an operator formalism for ambitwistor string theory is presented. It is shown how tree level supergravity scattering amplitudes are reco... Read More about Ambitwistor string theory in the operator formalism.

Lattice gerbe theory (2014)
Journal Article

We formulate the theory of a 2-form gauge field on a Euclidean spacetime lattice. In this approach, the fundamental degrees of freedom live on the faces of the lattice, and the action can be constructed from the sum over Wilson surfaces associated wi... Read More about Lattice gerbe theory.

Conformal field theories in six-dimensional twistor space (2012)
Journal Article
Mason, L., Reid-Edwards, R., & Taghavi-Chabert, A. (2012). Conformal field theories in six-dimensional twistor space. Journal of Geometry and Physics, 62(12), 2353-2375. https://doi.org/10.1016/j.geomphys.2012.08.001

This article gives a study of the higher-dimensional Penrose transform between conformally invariant massless fields on space–time and cohomology classes on twistor space, where twistor space is defined to be the space of projective pure spinors of t...

Non-geometric backgrounds, doubled geometry and generalised T-duality (2009)
Journal Article
Hull, C. M., & Reid-Edwards, R. A. (2009). Non-geometric backgrounds, doubled geometry and generalised T-duality. Journal of High Energy Physics, 2009(09), Article 014. https://doi.org/10.1088/1126-6708/2009/09/014

String backgrounds with a local torus fibration such as T-folds are naturally formulated in a doubled formalism in which the torus fibres are doubled to include dual coordinates conjugate to winding number. Here we formulate and explore a generalisat... Read More about Non-geometric backgrounds, doubled geometry and generalised T-duality.

Flux compactifications of string theory on twisted tori (2009)
Journal Article

Global aspects of Scherk‐Schwarz dimensional reduction are discussed and it is shown that it can usually be viewed as arising from a compactification on the compact space obtained by identifying a (possibly non‐compact) group manifold 𝒢 under a discr...

D-branes and doubled geometry (2009)

We define the open string version of the nonlinear sigma model on doubled geometry introduced by Hull and Reid-Edwards, and derive its boundary conditions. These conditions include the restriction of D-branes to maximally isotropic submanifolds as we... Read More about D-branes and doubled geometry.

Geometric and non-geometric compactifications of IIB supergravity (2008)
Journal Article

Complementary geometric and non-geometric consistent reductions of IIB supergravity are studied. The geometric reductions on the identified group manifold Script X = G/Γ are found to have a gauge symmetry with Lie algebroid structure, generalising th...

𝒩 = 4 gauged supergravity from duality-twist compactifications of string theory (2008)
Journal Article

We investigate the lifting of half-maximal four-dimensional gauged supergravities to compactifications of string theory. It is shown that a class of such supergravities can arise from compactifications of IIA string theory on manifolds of SU(2)-struc...

We apply canonical Poisson-Lie T-duality transformations to bosonic open string worldsheet boundary conditions, showing that the form of these conditions is invariant at the classical level, and therefore they are compatible with Poisson-Lie T-dualit...

We find the bosonic sector of the gauged supergravities that are obtained from 11-dimensional supergravity by Scherk-Schwarz dimensional reduction with flux to any dimension D. We show that, if certain obstructions are absent, the Scherk-Schwarz ansa... Read More about Flux compactifications of M-theory on twisted tori.
