Manyfield Inflation in Random Potentials
Theodor Bjorkmo, M. C. David Marsh
We construct models of inflation with many randomly interacting fields and use these to study the generation of cosmological observables. We model the potentials as multi-dimension…
Seven Lessons from Manyfield Inflation in Random Potentials
Mafalda Dias, Jonathan Frazer, M. C. David Marsh
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…
A New Bound on Axion-Like Particles
M. C. David Marsh, Helen R. Russell, Andrew C. Fabian +3
Axion-like particles (ALPs) and photons can quantum mechanically interconvert when propagating through magnetic fields, and ALP-photon conversion may induce oscillatory features in…
