We perform an exhaustive classification of G_2 invariant extrema of the most general gauged N=8 supergravity in four dimensions. They comprise four branches of Anti-de Sitter solutions labelled by a single parameter. Interestingly, while the gauge groups vary with the parameters, the mass spectra are invariant. One of these is a new non-supersymmetric yet stable point. Our analysis includes the recently proposed family of SO(8) gauged supergravities and more.

  1. Consistent truncations and G$_2$-invariant AdS$_4$ solutions of $D=11$ supergravity

    hep-th 2024-12 conditional novelty 6.0 of 10

    Three new G2-invariant AdS4 vacua of eleven-dimensional supergravity are found numerically, together with explicit uplift formulas and evidence that the G2-invariant sector may be complete.
