The non-linear dynamics of axion inflation: a detailed lattice study
Daniel G. Figueroa, Joanes Lizarraga, Nicolás Loayza +2
We study in detail the fully inhomogeneous non-linear dynamics of axion inflation, identifying three regimes: weak-, mild-, and strong-backreaction, depending on the duration of in…
