Primordial Power Spectrum and Bispectrum from Lattice Simulations of Axion-U(1) Inflation
Drew Jamieson, Angelo Caravano, Eiichiro Komatsu
We present primordial non-Gaussianity predictions from a new high-precision code for simulating axion-U(1) inflation on a discrete lattice. We measure the primordial scalar curvatu…
InflationEasy: A C++ Lattice Code for Inflation
Angelo Caravano
InflationEasy is a lattice code specifically developed for cosmological inflation. It simulates the nonlinear dynamics of a scalar field on a three-dimensional lattice in an expand…
Ultra-Slow-Roll Inflation on the Lattice II: Nonperturbative Curvature Perturbation
Angelo Caravano, Gabriele Franciolini, Sébastien Renaux-Petel
Building on the recent lattice simulations of ultra-slow-roll (USR) dynamics presented in arXiv:2410.23942, we investigate the role of the nonlinear relation between the inflaton f…
