  • A new class of de Sitter vacua in type IIB large volume compactifications 

    Gallego, Diego; Marsh, Carl Marc; Vercnocke, Bert; Wrase, Timm (JOURNAL OF HIGH ENERGY PHYSICS, 2017-10-26)

  • Inhomogeneous initial data and small-field inflation 

    Marsh, Carl Marc; Barrow, John David; Ganguly, C (IoPJournal of Cosmology and Astroparticle Physics, 2018-05-08)
    We consider the robustness of small-field inflation in the presence of scalar field inhomo- geneities. Previous numerical work has shown that if the scalar potential is flat only over a narrow in- terval, such as in commonly ...

  • Seven lessons from manyfield inflation in random potentials 

    Dias, Mafalda; Frazer, Jonathan; Marsh, Carl Marc (IoPJOURNAL OF COSMOLOGY AND ASTROPARTICLE PHYSICS, 2018-01)
    We study inflation in models with many interacting fields subject to randomly generated scalar potentials. We use methods from non-equilibrium random matrix theory to construct the potentials and an adaption of the ‘transport ...
