Dimensional Reduction for D3-brane Moduli
Brad Cownden, Andrew R. Frey, M. C. David Marsh +1
Warped string compactifications are central to many attempts to stabilize moduli and connect string theory with cosmology and particle phenomenology. We present a first-principles…
Universal Properties of Type IIB and F-theory Flux Compactifications at Large Complex Structure
M. C. David Marsh, Kepa Sousa
We consider flux compactifications of type IIB string theory and F-theory in which the respective superpotentials at large complex structure are dominated by cubic or quartic terms…
The Spectra of Type IIB Flux Compactifications at Large Complex Structure
Callum Brodie, M. C. David Marsh
We compute the spectra of the Hessian matrix, , and the matrix that governs the critical point equation of the low-energy effective supergravity, as a function…
Decoupling and de Sitter Vacua in Approximate No-Scale Supergravities
M. C. David Marsh, Bert Vercnocke, Timm Wrase
We study supergravity with chiral superfields in which one of the fields has a Kähler potential of exact no-scale type. Such systems admit de Sitter (dS) solutio…
Charting an Inflationary Landscape with Random Matrix Theory
M. C. David Marsh, Liam McAllister, Enrico Pajer +1
We construct a class of random potentials for N >> 1 scalar fields using non-equilibrium random matrix theory, and then characterize multifield inflation in this setting. By stipul…
