The Doubled Geometry of Nilmanifold Reductions
N. Chaemjumrus, C. M. Hull
A class of special holonomy spaces arise as nilmanifolds fibred over a line interval and are dual to intersecting brane solutions of string theory. Further dualities relate these t…
Degenerations of K3, Orientifolds and Exotic Branes
N. Chaemjumrus, C. M. Hull
A recently constructed limit of K3 has a long neck consisting of segments, each of which is a nilfold fibred over a line, that are joined together with Kaluza-Klein monopoles. The…
Heterotic/type II Duality and Non-Geometric Compactifications
Yoan Gautier, Chris M. Hull, Dan Israël
We present a new class of dualities relating non-geometric Calabi-Yau compactifications of type II string theory to T-fold compactifications of the heterotic string, both preservin…
Superstrings on AdS3 at k=1
G. Giribet, C. Hull, M. Kleban +2
We study superstring theory in three dimensional Anti-de Sitter spacetime with NS-NS flux, focusing on the case where the radius of curvature is equal to the string length. This co…
Generalised Geometry for M-Theory
C M Hull
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 generalise…
Doubled Geometry and T-Folds
C M Hull
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…
