SUMMARY:Three-dimensional flux vacua from Type II supergravities
DESCRIPTION:We discuss flux compactifications of Type IIA supergravity on G2 spaces with smeared O2/O6-planes down to three dimensions. We start by presenting the setup of allowed fluxes\, the internal geometry\, the equations of motion and after compactification we achieve N=1 AdS3 vacua with scale that can be parametrically decoupled from the KK modes. The solutions we find are at weak coupling and large volume regime while the moduli are fully stabilized at the classical level. Next\, utilizing the exact equations of motion including varying warp factor and dilaton we evaluate the backreaction of O6-planes. Using the appropriate flux scaling we show that the corrections to the various background fields are subleading when going from smeared to localized sources and we find the distances from the loci where the smeared approximation can be trusted. We discuss the possibility for de Sitter uplift as well as results of similar compactifications in Type IIB on curved internal G2 spaces.
