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…
T-Duality in Superspace
M. Abou-Zeid, C. M. Hull, U. Lindström +1
We find the T-duality transformation rules for 2-dimensional (2,1) supersymmetric sigma-models in (2,1) superspace. Our results clarify certain aspects of the (2,1) sigma model geo…
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…
Generalized Kähler Geometry in (2,1) superspace
Chris Hull, Ulf Lindström, Martin Roček +2
Two-dimensional (2,2) supersymmetric nonlinear sigma models can be described in (2,2), (2,1) or (1,1) superspaces. Each description emphasizes different aspects of generalized Kähl…
