Unity of superstring dualities

- C. Hull, P. Townsend
- Physics
- 21 October 1994

Abstract The effective action for type II string theory compactified on a six-torus is N = 8 supergravity, which is known to have an E7 duality symmetry. We show that this is broken by quantum… Expand

A geometry for non-geometric string backgrounds

- C. Hull
- Physics, Mathematics
- 11 June 2004

A geometric string solution has background fields in overlapping coordinate patches related by diffeomorphisms and gauge transformations, while for a non-geometric background this is generalised to… Expand

Twisted multiplets and new supersymmetric non-linear σ-models☆☆☆★

Abstract A new D = 2 supersymmetric representation, the twisted chiral multiplet, is derived. Describing spins zero and one-half, the twisted multiplet is used to formulate supersymmetric nonlinear… Expand

All supersymmetric solutions of minimal supergravity in five- dimensions

- J. Gauntlett, J. Gutowski, C. Hull, S. Pakis, H. Reall
- Physics
- 13 September 2002

All purely bosonic supersymmetric solutions of minimal supergravity in five dimensions are classified. The solutions preserve either one half or all of the supersymmetry. Explicit examples of new… Expand

Double Field Theory

- C. Hull, B. Zwiebach
- Physics
- 29 April 2009

The zero modes of closed strings on a torus — the torus coordinates plus dual coordinates conjugate to winding number — parameterize a doubled torus. In closed string field theory, the string field… Expand

Generalized metric formulation of double field theory

- O. Hohm, C. Hull, B. Zwiebach
- Physics
- 24 June 2010

The generalized metric is a T-duality covariant symmetric matrix constructed from the metric and two-form gauge field and arises in generalized geometry. We view it here as a metric on the doubled… Expand

Generalised geometry for M-theory

- C. Hull
- Physics, Mathematics
- 22 January 2007

Generalised geometry studies structures on a d-dimensional manifold with a metric and 2-form gauge field on which there is a natural action of the group SO(d, d). This is generalised to d-dimensional… Expand

Timelike T-duality, de Sitter space, large N gauge theories and topological field theory

- C. Hull
- Physics
- 17 June 1998

T-Duality on a timelike circle does not interchange IIA and IIB string theories, but takes the IIA theory to a type IIB* theory and the IIB theory to a type IIA* theory. The type II* theories admit… Expand

Doubled geometry and T-folds

- C. Hull
- Physics
- 15 May 2006

The doubled formulation of string theory, which is T-duality covariant and enlarges spacetime with extra coordinates conjugate to winding number, is reformulated and its geometric and topological… Expand

Duality and the signature of space-time

- C. Hull
- Physics
- 17 July 1998

Versions of M-theory are found in spacetime signatures (9,2) and (6,5), in addition to the usual M-theory in 10+1 dimensions, and these give rise to type IIA string theories in 10-dimensional… Expand
