All-orders moduli for type II flux backgrounds
George R. Smith, David Tennyson, Daniel Waldram
We investigate the old problem of determining the exact bulk moduli of generic -structure flux backgrounds of type II string theory. Using techniques from generalis…
BPS complexes and Chern--Simons theories from -structures in gauge theory and gravity
Julian Kupka, Charles Strickland-Constable, Eirik Eik Svanes +2
We consider a variety of physical systems in which one has states that can be thought of as generalised instantons. These include Yang--Mills theories on manifolds with a torsion-f…
A heterotic Kodaira-Spencer theory at one-loop
Anthony Ashmore, Javier José Murgas Ibarra, David Duncan McNutt +4
We consider a heterotic version of six-dimensional Kodaira-Spencer gravity derived from the heterotic superpotential. We compute the one-loop partition function and find it can be…
Brane wrapping, AKSZ sigma models, and QP manifolds
Alex S. Arvanitakis, David Tennyson
We introduce a technique to realise brane wrapping and double dimensional reduction in the context of AKSZ topological sigma models and also in their target spaces, which are sympl…
Romans massive QP manifolds
Alex S. Arvanitakis, Emanuel Malek, David Tennyson
We introduce QP manifolds that capture the generalised geometry of type IIA string backgrounds with Ramond-Ramond fluxes and Romans mass. Each of these is associated to a BPS brane…
Topological G and Spin(7) strings at 1-loop from double complexes
Anthony Ashmore, André Coimbra, Charles Strickland-Constable +2
We study the topological and strings at 1-loop. We define new double complexes for supersymmetric NSNS backgrounds of string theory using generalised geometry. The…
Exceptional complex structures and the hypermultiplet moduli of 5d Minkowski compactifications of M-theory
David Tennyson, Daniel Waldram
We present a detailed study of a new mathematical object in generalised geometry called an `exceptional complex structure' (ECS). It is the…
Heterotic backgrounds via generalised geometry: moment maps and moduli
Anthony Ashmore, Charles Strickland-Constable, David Tennyson +1
We describe the geometry of generic heterotic backgrounds preserving minimal supersymmetry in four dimensions using the language of generalised geometry. They are characterised by…
Generalising G geometry: involutivity, moment maps and moduli
Anthony Ashmore, Charles Strickland-Constable, David Tennyson +1
We analyse the geometry of generic Minkowski , flux compactifications in string theory, the default backgrounds for string model building. In M-theory they are…
