Generalised U-dual solutions in supergravity
Chris D. A. Blair, Sofia Zhidkova
We discuss the notion of generalised U-duality as a solution generating technique in supergravity. We demonstrate a method to take solutions of type IIA supergravity on a 3-sphere,…
A QP perspective on topology change in Poisson-Lie T-duality
Alex S. Arvanitakis, Chris D. A. Blair, Daniel C. Thompson
We describe topological T-duality and Poisson-Lie T-duality in terms of QP (differential graded symplectic) manifolds and their canonical transformations. Duality is mediated by a…
Non-Riemannian isometries from double field theory
Chris D. A. Blair, Gerben Oling, Jeong-Hyuck Park
We explore the notion of isometries in non-Riemannian geometries. Such geometries include and generalise the backgrounds of non-relativistic string theory, and they can be naturall…
Exploring Exceptional Drinfeld Geometries
Chris D. A. Blair, Daniel C. Thompson, Sofia Zhidkova
We explore geometries that give rise to a novel algebraic structure, the Exceptional Drinfeld Algebra, which has recently been proposed as an approach to study generalised U-dualit…
Non-relativistic duality and deformations
Chris D. A. Blair
We make some observations connecting non-relativistic limits of string theory with deformations and TsT transformations.
A worldsheet supersymmetric Newton-Cartan string
Chris D. A. Blair
We construct a (locally) supersymmetric worldsheet action for a string in a non-relativistic Newton-Cartan background. We do this using a doubled string action, which describes the…
