DOI: 10.1103/physrevd.107.083503
Abstract: We consider coupled dark energy (CDE) cosmologies, where dark matter particles feel a force stronger than gravity, due to the fifth force mediated by a scalar field which plays the role of dark energy. We… read more here.

DOI: 10.1103/physrevd.95.043526
Abstract: Dynamical Dark Matter (DDM) is an alternative framework for dark-matter physics in which the dark sector comprises a vast ensemble of particle species whose decay widths are balanced against their cosmological abundances. Previous studies of… read more here.

DOI: 10.1103/physrevd.99.064051
Abstract: The main goal of this work is to propose a generalized model of interacting dark energy which allows for the kinetic term of a scalar field to couple to the matter species a priori in… read more here.
