Three-dimensional flux vacua from IIB on co-calibrated G2 orientifolds
Three-dimensional flux vacua from IIB on co-calibrated G2 orientifolds
We derive the 3D N = 1 superpotential for the closed string sector of type IIB supergravity on toroidal O5 orientifolds with co-calibrated G2 structure and RR background flux. We find that such compactifications can provide full closed string moduli stabilization on supersymmetric $$\hbox {AdS}_3$$ vacua, and once we include …
