From black holes to flux throats

Abstract

Supersymmetry‐breaking is a key ingredient for string theory models to be phenomenologically viable. We review the strong analogy in the physics and methods used for describing non‐supersymmetric flux vacua and non‐supersymmetric black holes in string theory. We also show how the polarized state could be the key to describing a well‐behaved back‐reaction of anti‐branes in flux backgrounds, shedding a new light on a recent debate in the literature.

De Sitter vs Quintessence in String Theory

“…Finally an EFT analysis of the anti‐brane singularity has been done for the simplest case of one single anti‐brane (which is sufficient to achieve dS) for which the probe approximation is under control and no divergences are found, so addressing the anti‐brane induced singularity problem . The same conclusion has been reached recently using different techniques …”

Gravity and on-shell probe actions

“…Related and extremely instructive results using probe branes in holographic set-ups have also appeared in the earlier literature [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37].…”
