On the maximal superalgebras of supersymmetric backgrounds
José Figueroa-O'Farrill, Emily Hackett-Jones, George Moutsopoulos +1
In this note we give a precise definition of the notion of a maximal superalgebra of certain types of supersymmetric supergravity backgrounds, including the Freund-Rubin background…
Quantum Mechanics of the Doubled Torus
Emily Hackett-Jones, George Moutsopoulos
We investigate the quantum mechanics of the doubled torus system, introduced by Hull [1] to describe T-folds in a more geometric way. Classically, this system consists of a world-s…
On T-folds, G-structures and Supersymmetry
James Gray, Emily Hackett-Jones
We describe how to calculate the amount of supersymmetry associated to a class of supergravity theories obtained by compactification on T-folds. We illustrate our discussion by cal…
Type IIB Killing spinors and calibrations
Emily J. Hackett-Jones, Douglas J. Smith
In this paper we derive the full set of differential equations and some algebraic relations for p-forms constructed from type IIB Killing spinors. These equations are valid for the…
Topological charges for branes in M-theory
Emily J. Hackett-Jones, David C. Page, Douglas J. Smith
We propose a simple form for the superalgebra of M2 and M5-brane probes in arbitrary supersymmetric backgrounds of 11D supergravity, extending previous results in the literature. I…
