The existence of AdS vacua in string theory with a parametric separation between the Hubble scale and the Kaluza-Klein scale of the extra dimensions is an open question, and holography is a promising tool to tackle this. I will discuss some remarkable features of the holographic CFT duals of the DGKT vacua, which are candidate AdS vacua with parametric scale separation.
The integrability program provides powerful tools to determine the spectrum of holographic theories. The development of these tools and the generalisation to a wider scope of theories go hand in hand. In particular, non-supersymmetric versions of AdS/CFT can be accessed, which is a first step towards more realistic models of QCD and could shed some light on SUSY-breaking mechanisms needed for...
