Strong primordial inhomogeneities induced by axion-like scalar field
arXiv:2502.12610
Abstract
Our goal is to consider Axion-like particle (ALP) model to investigate the behaviour of space-time in the vicinity of the domain wall, induced by axion-like field. Here we present first-step approximation in our analysis and discuss the applicability of thin-shell approximation.
