On the DGKT brane dual and its decoupling
Fien Apers
It is not understood whether scale-separated AdS vacua in string theory admit a holographic dual. A well-known class of such vacua is provided by the DGKT solutions of massive type…

Backtracking AdS flux vacua
Fien Apers, Miguel Montero, Irene Valenzuela
We introduce an algorithm (dubbed "flux backtracking") to reverse-engineer the brane picture from an AdS flux vacuum. Given an AdS flux vacuum as input, the algorithm outputs a sin…
