Hyperinflation generalised: from its attractor mechanism to its tension with the `swampland conjectures'
Theodor Bjorkmo, M. C. David Marsh
In negatively curved field spaces, inflation can be realised even in steep potentials. Hyperinflation invokes the `centrifugal force' of a field orbiting the hyperbolic plane to su…

The Swampland, Quintessence and the Vacuum Energy
M. C. David Marsh
It has recently been conjectured that string theory does not admit de Sitter vacua, and that quintessence explains the current epoch of accelerated cosmic expansion. A proposed, ke…

A New Class of de Sitter Vacua in Type IIB Large Volume Compactifications
Diego Gallego, M. C. David Marsh, Bert Vercnocke +1
We construct a new class of metastable de Sitter vacua of flux compactifications of type IIB string theory. These solutions provide a natural extension of the `Large Volume Scenari…
