Effective potentials, warping, and implications for F-term uplifting
Arthur Hebecker, Severin Lüst, Andreas Schachner +1
We analyse warping corrections to the scalar potential in flux compactifications of Type IIB string theory, focusing on their effect on -term de Sitter uplifting in Calabi-Yau o…
More Effective RS Field Theory
Severin Lüst, Michael Nee, Lisa Randall
In this paper we derive the effective theory for a stabilized five-dimensional warped geometry, addressing several outstanding issues in this derivation. These include allowing for…
Species Quantum Mechanics
Luis A. Anchordoqui, Dieter Lust, Severin Lüst
In this note we introduce some concepts of Species Quantum Mechanics. Specifically, we consider quantum operators that correspond to the species number and the tower mass sca…
KKLT Ex Nihilo
Iosif Bena, Yixuan Li, Severin Lüst
Flux compactifications that give three- or four-dimensional Anti de Sitter vacua with a parametrically small negative cosmological constant are claimed to be ubiquitous in String T…
An index for flux vacua
Severin Lüst
We propose to use the winding number of the gradient of a scalar potential as a simple topological index that relates critical points in the interior of the scalar field space to t…
On the cosmological constant, the KK mass scale, and the cut-off dependence in the dark dimension scenario
Luis A. Anchordoqui, Ignatios Antoniadis, Dieter Lust +1
In this short note we comment on the relation between the cosmological and the Kaluza-Klein mass scale in the dark dimension scenario, also in view of some recent claims that would…
