Fate of homogeneous \mathbb{Z}_2-symmetric scalar condensates

Dark matter, if represented by a \mathbb{Z}_2-symmetric scalar field, can manifest as both particles and condensates. In this paper, we study the evolution of an oscillating homogeneous condensate of a \mathbb{Z}_2-symmetric scalar field in a thermal plasma in an FLRW universe. We focus on the perturbative regime where the oscillation... Show more
