%0 Journal Article %T New supersymmetric vacua on solvmanifolds %A David Andriot %J Mathematics %D 2015 %I arXiv %X We obtain new supersymmetric flux vacua of type II supergravities on four-dimensional Minkowski times six-dimensional solvmanifolds. The orientifold O4, O5, O6, O7, or O8-planes and D-branes are localized. All but one vacua are in addition not T-dual to a vacuum on the torus. The corresponding solvmanifolds are proven to be Calabi-Yau, with explicit metrics. Other Ricci flat solvmanifolds are shown to be only K\"ahler. %U http://arxiv.org/abs/1507.00014v1
