Consistent Truncations and Dualities
Daniel Butter, Falk Hassler, Christopher N. Pope +1
Recent progress in generalised geometry and extended field theories suggests a deep connection between consistent truncations and dualities, which is not immediately obvious. A pri…
Type II Double Field Theory in Superspace
Daniel Butter
We explore type II supersymmetric double field theory in superspace. The double supervielbein is an element of the orthosymplectic group OSp(10,10|64), which also governs the struc…
Notes on Ramond-Ramond spinors and bispinors in double field theory
Daniel Butter
The Ramond-Ramond sector of double field theory (DFT) can be described either as an O(D,D) spinor or an O(D-1,1) x O(1,D-1) bispinor. Both formulations may be related to the standa…
Linearized Off-shell 4+7 Supergeometry of 11D Supergravity
Katrin Becker, Daniel Butter, Anindya Sengupta
We describe the linearized supergeometry of eleven dimensional supergravity with four off-shell local supersymmetries. We start with a background Minkowski 11D, N=1 superspace, and…
