Tendimensional origin of Minkowski vacua in N = 8 supergravity
Abstract
Maximal supergravity in four dimensions admits two inequivalent dyonic gaugings of the group SO(4)×SO(2,2) ⋉T^{16}. 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 fourdimensional theories arise as consistent truncations from IIA and IIB supergravity, respectively, around a Mink^{4}×S^{3} ×H^{3} geometry. The IIA/IIB truncations are efficiently related by an outer automorphism of SL(4) ⊂ E_{7(7)}. As an application, we give an explicit uplift of the moduli of the vacua into a 4parameter family of tendimensional solutions.
