Lattice simulations of Abelian gauge fields coupled to axions during Inflation
Angelo Caravano, Eiichiro Komatsu, Kaloian D. Lozanov +1
We use a lattice simulation to study a model of axion inflation where the inflaton is coupled to a U(1) gauge field through Chern-Simons interaction. These kinds of models have alr…
Lattice Simulations of Inflation
Angelo Caravano, Eiichiro Komatsu, Kaloian D. Lozanov +1
The scalar field theory of cosmological inflation constitutes nowadays one of the preferred scenarios for the physics of the early universe. In this paper we aim at studying the in…
Combining cosmological and local bounds on bimetric theory
Angelo Caravano, Marvin Lüben, Jochen Weller
Ghost-free bimetric theory describes two nonlinearly interacting spin-2 fields, one massive and one massless, thus extending general relativity. We confront bimetric theory with ob…
