Supersymmetric Vacua in Random Supergravity
Thomas C. Bachlechner, David Marsh, Liam McAllister +1
We determine the spectrum of scalar masses in a supersymmetric vacuum of a general N=1 supergravity theory, with the Kahler potential and superpotential taken to be random function…
Superpotential de-sequestering in string models
Marcus Berg, Joseph P. Conlon, David Marsh +1
Non-perturbative superpotential cross-couplings between visible sector matter and Kähler moduli can lead to significant flavour-changing neutral currents in compactifications of ty…
Cosmology of Axions and Moduli: A Dynamical Systems Approach
David J. E. Marsh, Ewan R. M. Tarrant, Edmund J. Copeland +1
This paper is concerned with string cosmology and the dynamics of multiple scalar fields in potentials that can become negative, and their features as (Early) Dark Energy models. O…
The Wasteland of Random Supergravities
David Marsh, Liam McAllister, Timm Wrase
We show that in a general \cal{N} = 1 supergravity with N \gg 1 scalar fields, an exponentially small fraction of the de Sitter critical points are metastable vacua. Taking the sup…
