Description
Axion inflation remains one of the most compelling scenarios for early-universe dynamics, offering distinctive observational signatures. In this talk, I will present our recent work on the strong backreaction regime in abelian axion inflation, using fully self-consistent lattice simulations to capture the non-linear dynamics. Particular attention will be given to possible extensions to more general inflationary potentials. I will also present our first steps toward modelling the resulting gravitational wave signal and discuss the prospects for future observational detection.
