1. New dual gravitational charges / Godazgar, Hadi ; Godazgar, Mahdi ; Pope, C. N.
We show that there are a further infinite number of, previously unknown, supertranslation charges. [...]

2. Entanglement entropy, the Einstein equation and the Sparling construction / Godazgar, Mahdi
We relate the recent derivation of the linearised Einstein equation on an AdS background from holographic entanglement entropy arguments to the Sparling construction: we derive the differential form whose exterior derivative gives the Einstein equation from the Sparling formalism. [...]

3. Consistent 4-form fluxes for maximal supergravity / Godazgar, Hadi ; Godazgar, Mahdi ; Krüger, Olaf ; Nicolai, Hermann
We derive new ansätze for the 4-form field strength of D = 11 supergravity corresponding to uplifts of four-dimensional maximal gauged supergravity. [...]

4. An SO(3)×SO(3) invariant solution of D = 11 supergravity / Godazgar, Hadi ; Godazgar, Mahdi ; Krüger, Olaf ; Nicolai, Hermann ; et al
We construct a new SO(3)×SO(3) invariant non-supersymmetric solution of the bosonic field equations of D = 11 supergravity from the corresponding stationary point of maximal gauged N = 8 supergravity by making use of the non-linear uplift formulae for the metric and the 3-form potential. [...]

5. Supersymmetric E 7(7) exceptional field theory / Hadi Godazgar ; Mahdi Godazgar ; Olaf Hohm ; Hermann Nicolai ; et al
We give the supersymmetric extension of exceptional field theory for E 7(7) , which is based on a (4 + 56)-dimensional generalized spacetime subject to a covariant constraint. [...]

6. Einstein-Cartan calculus for exceptional geometry / Hadi Godazgar ; Mahdi Godazgar ; Hermann Nicolai
In this paper we establish and clarify the link between the recently found E 7(7) generalised geometric structures, which are based on the SU(8) invariant reformulation of D = 11 supergravity proposed long ago, and newer results obtained in the framework of recent approaches to generalised geometry, where E 7(7) duality is built in and manifest from the outset.

7. Generalised geometry from the ground up / Hadi Godazgar ; Mahdi Godazgar ; Hermann Nicolai
Extending previous work on generalised geometry, we explicitly construct an E 7(7) -valued vielbein in eleven dimensions that encompasses the would be scalar bosonic degrees of freedom after reduction to four dimensions of D = 11 supergravity, by identifying new “generalised vielbeine” in eleven dimensions associated with the dual 6-form potential and the dual graviton.
