Simulating the inflationary Universe: from single-field to the axion-U(1) model
Angelo Caravano
We present a nonlinear study of the inflationary epoch based on numerical lattice simulations. Lattice simulations are a well-known tool in primordial cosmology, and they have been…

Lattice Simulations of Axion-U(1) Inflation
Angelo Caravano, Eiichiro Komatsu, Kaloian D. Lozanov +1
We present the first nonlinear lattice simulation of an axion field coupled to a U(1) gauge field during inflation. We use it to fully characterize the statistics of the primordial…
