Generation of Coherent Structures After Cosmic Inflation
Marcelo Gleiser, Noah Graham, Nikitas Stamatopoulos
We investigate the nonlinear dynamics of hybrid inflation models, which are characterized by two real scalar fields interacting quadratically. We start by solving numerically the c…

Emergence of Oscillons in an Expanding Background
E. Farhi, N. Graham, A. H. Guth +3
We consider a (1+1) dimensional scalar field theory that supports oscillons, which are localized, oscillatory, stable solutions to nonlinear equations of motion. We study this theo…

Unnatural Oscillon Lifetimes in an Expanding Background
N. Graham, N. Stamatopoulos
We consider a classical toy model of a massive scalar field in 1+1 dimensions with a constant exponential expansion rate of space. The nonlinear theory under consideration supports…
