Ten-dimensional origin of Minkowski vacua in N=8 supergravity

Ten-dimensional origin of Minkowski vacua in N=8 supergravity

Maximal supergravity in four dimensions admits two inequivalent dyonic gaugings of the group SO(4)×SO(2,2)⋉T16. Both admit a Minkowski vacuum with residual SO(4)×SO(2)2 symmetry and identical spectrum. We explore these vacua and their deformations. Using exceptional field theory, we show that the fo...
