Low-energy brane decoupling in AdS flux vacua
Fien Apers, Noelia Sánchez González
We study the decoupling of branes sourcing AdS flux vacua from the asymptotic bulk using scalar-wave absorption probabilities. In a one-modulus truncation, the result depends only…
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…
A Note on 4d Kination and Higher-Dimensional Uplifts
Fien Apers, Joseph P. Conlon, Martin Mosny
This note expands on the details of the relationship between 4d kination solutions in string cosmology and Kasner solutions of 10d general relativity. It extends previous analyses…
String Theory and the First Half of the Universe
Fien Apers, Joseph P. Conlon, Edmund J. Copeland +2
We perform a detailed study of stringy moduli-driven cosmologies between the end of inflation and the commencement of the Hot Big Bang, including both the background and cosmologic…
Kination, Meet Kasner: On The Asymptotic Cosmology of String Compactifications
Fien Apers, Joseph P. Conlon, Martin Mosny +1
We study runaway, kination-dominated epochs in string cosmology. We show how the apparent classical decompactification runaway of the volume modulus, described by a kination epoch…
Aspects of AdS flux vacua with integer conformal dimensions
Fien Apers
The DGKT vacua are a class of AdS flux vacua showing full moduli stabilization, parametric control, and a parametric separation of scales. The particular masses of the moduli r…
Integer Conformal Dimensions for Type IIA Flux Vacua
Fien Apers, Joseph P. Conlon, Sirui Ning +1
We give a concise argument that supersymmetric AdS type IIA DGKT flux vacua on general Calabi-Yaus have, interpreted holographically, integer conformal dimensions for low-lying sca…
Comments on classical AdS flux vacua with scale separation
Fien Apers, Miguel Montero, Thomas Van Riet +1
AdS flux vacua with a parametric separation between the AdS and KK scales have been conjectured to be in the Swampland. We study flux compactifications of massive IIA supergravity…
