An M-theory solution from null roots in E11
Laurent Houart, Axel Kleinschmidt, Josef Lindman Hörnlund
We find a purely gravitational classical solution of M-theory/eleven-dimensional supergravity which corresponds to a solution of the E10 brane sigma-model involving a null root. Th…
Some Algebraic Aspects of Half-BPS Bound States in M-Theory
Laurent Houart, Axel Kleinschmidt, Josef Lindman Hörnlund
We revisit non-marginal half-BPS solutions of M-theory in the framework of the possible existence of an underlying E11 Kac-Moody symmetry. In this context, non-marginal BPS solutio…
Finite and infinite-dimensional symmetries of pure N=2 supergravity in D=4
Laurent Houart, Axel Kleinschmidt, Josef Lindman Hörnlund +2
We study the symmetries of pure N=2 supergravity in D=4. As is known, this theory reduced on one Killing vector is characterised by a non-linearly realised symmetry SU(2,1) which i…
Boosting Taub-NUT to a BPS NUT-wave
Riccardo Argurio, François Dehouck, Laurent Houart
The boosted Taub-NUT metric with zero ADM mass is shown to possess a dual momentum in the direction of the boost giving credit to the existence of another 4-vector K_μin linearized…
Supersymmetry and Gravitational Duality
Riccardo Argurio, François Dehouck, Laurent Houart
We study how the supersymmetry algebra copes with gravitational duality. As a playground, we consider a charged Taub-NUT solution of D=4, N=2 supergravity. We find explicitly its K…
The emergence of fermions and the E11 content
Francois Englert, Laurent Houart
Claudio's warm and endearing personality adds to our admiration for his achievements in physics a sense of friendliness. His constant interest in fundamental questions motivated th…
