Abstract In this short paper, we will review the proposal of a correspondence between the doubled geometry of Double Field Theory and the higher geometry of bundle gerbes. Double Field Theory is T-duality covariant formulation of the supergravity limit of String Theory, which generalises Kaluza-Klein theory by unifying metric and Kalb-Ramond field on a doubled-dimensional space. In light of the proposed correspondence, this doubled geometry is interpreted as an atlas description of the higher…

Algebroids, AKSZ Constructions and Doubled Geometry

Abstract We give a self-contained survey of some approaches aimed at a global description of the geometry underlying double field theory. After reviewing the geometry of Courant algebroids and their

Gerbes in Geometry, Field Theory, and Quantisation

Abstract This is a mostly self-contained survey article about bundle gerbes and some of their recent applications in geometry, field theory, and quantisation. We cover the definition of bundle gerbes



Global Double Field Theory is Higher Kaluza‐Klein Theory

Kaluza‐Klein Theory states that a metric on the total space of a principal bundle P→M , if it is invariant under the principal action of P, naturally reduces to a metric together with a gauge field

Towards a double field theory on para-Hermitian manifolds

In a previous paper, we have shown that the geometry of double field theory has a natural interpretation on flat para-Kahler manifolds. In this paper, we show that the same geometric constructions

Doubled geometry and T-folds

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 and topological

Double field theory on group manifolds

A bstractA new version of double field theory (DFT) is derived for the exactly solvable background of an in general left-right asymmetric WZW model in the large level limit. This generalizes the

Generalised kinematics for double field theory

A bstractWe formulate a kinematical extension of Double Field Theory on a 2d-dimensional para-Hermitian manifold Pηω$$ \left(\mathcal{P},\eta, \omega \right) $$ where the O(d, d) metric η is

M-theory, exceptional generalised geometry and superpotentials

We discuss the structure of "exceptional generalised geometry" (EGG), an extension of Hitchin's generalised geometry that provides a unified geometrical description of backgrounds in

Fluxes, bundle gerbes and 2-Hilbert spaces

We elaborate on the construction of a prequantum 2-Hilbert space from a bundle gerbe over a 2-plectic manifold, providing the first steps in a programme of higher geometric quantisation of closed

Poisson-Lie U-duality in exceptional field theory

Poisson-Lie duality provides an algebraic extension of conventional Abelian and non-Abelian target space dualities of string theory and has seen recent applications in constructing quantum group

Para‐Hermitian Geometry, Dualities and Generalized Flux Backgrounds

We survey physical models which capture the main concepts of double field theory on para‐Hermitian manifolds. We show that the geometric theory of Lagrangian and Hamiltonian dynamical systems is an
