Résumé |
There have been several proposals of scale-separated AdS vacua in the literature.
All known examples arise from the effective field theory of flux
compactifications with low supersymmetry, and there are often doubts about
their consistency as ten or eleven-dimensional backgrounds in string theory.
These issues can often be tackled in the bulk theory, or by analysis of the dual
CFT via holography. I will review the most common issues, and focus the analysis
on the recently constructed family of 3d scale-separated AdS vacua, which is dual
to a two-dimensional CFT, emphasizing the discrete symmetry structure of the model
in comparison to DGKT. Finally, I will comment on the tantalizing observation of
integer operator dimensions in DGKT-like vacua, and comment on possible places to
look for consistency issues in these models. |
