E_7 ExFT in superspace [UNUSUAL TIME!]

Abstract: Exceptional field theory (ExFT) provides a framework where T and U-duality can be made manifest. In this talk, I will discuss how supersymmetry can also be made manifest in a superspace ExFT. In this approach, the fermionic coordinates are unified with the external spacetime coordinates, which together are acted on by external superdiffeomorphisms. The internal space and its section condition remain purely bosonic. This corresponds to the simplest way one might construct an exceptional superspace, but even this proves surprising: it cannot be done directly with the original supersymmetric formulations of ExFT, and one must instead relax or reformulate certain features (such as the vielbein postulates). I will sketch how this works for the case of E_7. The superspace Bianchi identities then lead to the explicit form of the on-shell p-form curvatures as well as their duality relations. Various applications will also be discussed.
