E7(7) symmetry in perturbatively quantised N=8 supergravity
Guillaume Bossard, Christian Hillmann, Hermann Nicolai
We study the perturbative quantisation of N=8 supergravity in a formulation where its E7(7) symmetry is realised off-shell. Relying on the cancellation of SU(8) current anomalies w…
E7(7) invariant Lagrangian of d=4 N=8 supergravity
Christian Hillmann
We present an E7(7) invariant Lagrangian that leads to the equations of motion of d=4 N=8 supergravity without using Lagrange multipliers. The superinvariance of this new action an…
Fermionic Kac-Moody Billiards and Supergravity
Thibault Damour, Christian Hillmann
We study the "fermionic billiards", i.e. the chaotic dynamics of the gravitino, that arise in the near-spacelike-singularity limit of eleven-dimensional supergravity and of its dim…
E(7(7)) and d=11 supergravity
Christian Hillmann
This thesis firstly investigates whether D=11 supergravity can be lifted to a higher dimensional theory without introducing additional bosonic fields by interpreting the E(7(7))-sy…
Generalized E(7(7)) coset dynamics and D=11 supergravity
Christian Hillmann
The hidden on-shell E(7(7)) symmetry of maximal supergravity is usually discussed in a truncation from D=11 to four dimensions. In this article, we reverse the logic and start from…
Pure type I supergravity and DE(10)
Christian Hillmann, Axel Kleinschmidt
We establish a dynamical equivalence between the bosonic part of pure type I supergravity in D=10 and a D=1 non-linear sigma-model on the Kac-Moody coset space DE(10)/K(DE(10)) if…
