Double field theory: a pedagogical review

G Aldazabal, D Marques, C Nunez - Classical and Quantum …, 2013 - iopscience.iop.org
Double field theory (DFT) is a proposal to incorporate T-duality, a distinctive symmetry of
string theory, as a symmetry of a field theory defined on a double configuration space. The …

Duality symmetric string and M-theory

DS Berman, DC Thompson - Physics Reports, 2015 - Elsevier
We review recent developments in duality symmetric string theory. We begin with the world-
sheet doubled formalism which describes strings in an extended spacetime with extra …

Spheres, generalised parallelisability and consistent truncations

K Lee, C Strickland‐Constable… - Fortschritte der …, 2017 - Wiley Online Library
We show that generalised geometry gives a unified description of maximally supersymmetric
consistent truncations of ten‐and eleven‐dimensional supergravity. In all cases the …

Consistent Kaluza-Klein truncations via exceptional field theory

O Hohm, H Samtleben - Journal of High Energy Physics, 2015 - Springer
A bstract We present the generalized Scherk-Schwarz reduction ansatz for the full
supersymmetric exceptional field theory in terms of group valued twist matrices subject to …

Kerr-Schild double field theory and classical double copy

K Lee - Journal of High Energy Physics, 2018 - Springer
A bstract The Kerr-Schild (KS) formalism is a powerful tool for constructing exact solutions in
general relativity. In this paper, we present a generalization of the conventional KS …

T-duality and α′-corrections

D Marqués, CA Nunez - Journal of High Energy Physics, 2015 - Springer
A bstract We construct an O (d, d) invariant universal formulation of the first-order α′-
corrections of the string effective actions involving the dilaton, metric and two-form fields …

Classification of non-Riemannian doubled-yet-gauged spacetime

K Morand, JH Park - The European Physical Journal C, 2017 - Springer
Abstract Assuming O (D, D) O (D, D) covariant fields as the 'fundamental'variables, double
field theory can accommodate novel geometries where a Riemannian metric cannot be …

Heterotic Kerr-Schild double field theory and classical double copy

W Cho, K Lee - Journal of High Energy Physics, 2019 - Springer
A bstract We discuss the generalization of the Kerr-Schild (KS) formalism for general
relativity and double field theory (DFT) to the heterotic DFT and supergravity. We first …

Half‐Maximal Supersymmetry from Exceptional Field Theory

E Malek - Fortschritte der Physik, 2017 - Wiley Online Library
We study‐dimensional half‐maximal flux backgrounds using exceptional field theory. We
define the relevant generalised structures and also find the integrability conditions which …

Double field theory on group manifolds

R Blumenhagen, F Hassler, D Lüst - Journal of High Energy Physics, 2015 - Springer
A bstract A 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 …
