String theory in twistor space and minimal tension holography
N. M. McStay, R. A. Reid-Edwards
Explicit examples of the AdS/CFT correspondence where both bulk and boundary theories are tractable are hard to come by, but the minimal tension string on $AdS_3 \times S^3 \times…
Symmetries and Covering Maps for the Minimal Tension String on
N. M. McStay, R. A. Reid-Edwards
This paper considers a recently-proposed string theory on with one unit of NS-NS flux (). We discuss interpretations of the target space, including…
Operator Deformations and T-duality via Parallel Transport
Hasan Mahmood, R. A. Reid-Edwards
We consider deformations of CFTs from the perspective of parallel transport in moduli space. In particular, we show how the deformations of individual operators can be computed and…
Torus Bundles, Automorphisms and T-Duality
Hasan Mahmood, R. A. Reid-Edwards
We reconsider some older constructions of T-duality, based on automorphisms of the worldsheet operator algebra, in a modern context. It has been long known that at special points i…
An Alternative Perspective on Ambitwistor String Theory
N. Carabine, R. A. Reid-Edwards
We review some ideas on the relationship between massless superparticles and the division algebras to provide a new perspective on ambitwsitor string theories. The key concern is t…
A Superstring Field Theory for Supergravity
R. A. Reid-Edwards, D. A. Riccombeni
A covariant closed superstring field theory, equivalent to classical ten-dimensional Type II supergravity, is presented. The defining conformal field theory is the ambitwistor stri…
Ambitwistor String Theory in the Operator Formalism
R. A. Reid-Edwards
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 superg…
Lattice Gerbe Theory
Arthur E. Lipstein, Ronald A. Reid-Edwards
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 act…
The supersymmetric Penrose transform in six dimensions
L. J. Mason, R. A. Reid-Edwards
We give a supersymmetric extension to the six-dimensional Penrose transform and give an integral formula for the on-shell (0, 2) supermultiplet. The relationship between super fiel…
On Closed Twistor String Theory
R. A. Reid-Edwards
The Heterotic twistor string theory of Mason and Skinner is investigated with particular attention given to the role of topological gravity on the world-sheet. The general structur…
Conformal Field Theories in Six-Dimensional Twistor Space
L. J. Mason, R. A. Reid-Edwards, A. Taghavi-Chabert
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 tw…
On Type IIA geometries dual to N = 2 SCFTs
R. A. Reid-Edwards, B. Stefanski
We provide explicit solutions of Type IIA supergravity which are believed to be dual to N = 2 superconformal four dimensional gauge theories. These explicit solutions are based on…
Bi-algebras, generalised geometry and T-duality
R. A. Reid-Edwards
A study of sigma models whose target space is a group G that admits a compatible Poisson structure is presented. The natural action of O(D,D;Z) on the generalised tangent bundle TG…
Flux compactifications, twisted tori and doubled geometry
R A Reid-Edwards
In arXiv:0902.4032 [hep-th] an O(D,D)-covariant sigma model describing the embedding of a closed world-sheet into the 2D-dimensional twisted torus was proposed. Such sigma models p…
N=4 Gauged Supergravity from Duality-Twist Compactifications of String Theory
R A Reid-Edwards, B Spanjaard
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 f…
D-branes and doubled geometry
Cecilia Albertsson, Tetsuji Kimura, Ronald A. Reid-Edwards
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…
Geometric and Non-Geometric Compactifications of IIB Supergravity
R. A. Reid-Edwards
Complimentary geometric and non-geometric consistent reductions of IIB supergravity are studied. The geometric reductions on the identified group manifold X are found to have a gau…
Worldsheet boundary conditions in Poisson-Lie T-duality
Cecilia Albertsson, Ronald A. Reid-Edwards
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 classi…
Flux Compactifications of M-Theory on Twisted Tori
C. M. Hull, R. A. Reid-Edwards
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…
Flux Compactifications of String Theory on Twisted Tori
C. M. Hull, R. A. Reid-Edwards
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…
