Seven lessons from manyfield inflation in random potentials
(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 ...
Inhomogeneous initial data and small-field inflation
(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 ...
ADHM and the 4d quantum Hall effect
(Journal of High Energy Physics, 2018-04-01)
© 2018, The Author(s). Yang-Mills instantons are solitonic particles in d = 4 + 1 dimensional gauge theories. We construct and analyse the quantum Hall states that arise when these particles are restricted to the lowest ...
