Q-ball perturbations with more details: linear analysis vs lattice
arXiv:2412.13885
Abstract
We analyze in detail the interactions between non-topological soliton (Q-ball) and its perturbations. We extend the previous literature by carefully identifying the domain of applicability of linear analysis as well discussion of the FLS Q-balls. Applications to the early universe physics are briefly commented.
