Warped Numerical Calabi-Yau Metrics
Severin Lüst, Fabian Ruehle, Simon Schreyer
We compute numerical warped Type IIB flux backgrounds on Calabi-Yau threefolds following the construction of Giddings, Kachru, and Polchinski. Using physics-informed neural network…
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…
Higher order corrections to KPV: The nonabelian brane stack perspective
Simon Schreyer
In this work, we study the decay of -branes in the setup of Kachru, Pearson, and Verlinde (KPV) at higher order in from the perspective of a nonabelian $\overli…
No Asymptotic Acceleration without Higher-Dimensional de Sitter Vacua
Arthur Hebecker, Simon Schreyer, Victoria Venken
There has recently been considerable interest in the question whether and under which conditions accelerated cosmological expansion can arise in the asymptotic regions of field spa…
corrections to KPV: An uplifting story
Simon Schreyer, Victoria Venken
In earlier work, the effect of curvature corrections on the NS5-brane responsible for the decay of anti-D3-branes in the set-up of Kachru, Pearson, and Verlinde (KPV) was co…
Curvature corrections to KPV: Do we need deep throats?
Arthur Hebecker, Simon Schreyer, Victoria Venken
We consider curvature corrections to the action of an NS5-brane which plays the key role in the metastability analysis of warped anti-D3-brane uplifts by Kachru, Pearson and…
Loops, Local Corrections and Warping in the LVS and other Type IIB Models
Xin Gao, Arthur Hebecker, Simon Schreyer +1
To establish metastable de Sitter vacua or even just scale-separated AdS, control over perturbative corrections to the string-derived leading-order 4d lagrangian is crucial. Such c…
The LVS Parametric Tadpole Constraint
Xin Gao, Arthur Hebecker, Simon Schreyer +1
The large volume scenario (LVS) for de Sitter compactifications of the type IIB string is, at least in principle, well protected from various unknown corrections. The reason is tha…
