Holographic Constraints on the String Landscape

Abstract: I will discuss scale separation in top-down string theory constructions of AdS vacua, focusing on proposals based on compactifications on Ricci-flat manifolds such as DGKT and KKLT. I will then present a general argument that the putative CFT duals of such scale-separated AdS vacua cannot emerge as infrared limits of any brane configuration in string theory, implying that such vacua are unlikely to be UV complete. This explains why stable AdS vacua in string theory are essentially higher-dimensional in nature. If time permits, I will conclude with further holographic constraints on scalar potentials with implications for cosmology.
