Non-minimal coupling of scalar fields in the dark sector and generalization of the top-hat collapse
Abstract In this article we propose a new way to handle interactions between two scalar fields, in the cosmological backdrop, where one scalar field oscillates rapidly in the cosmological time scale while the other one evolves without showing any periodic behavior. We have interpreted the rapidly os...
