Phases of the Bose-Einstein condensate dark matter model with both two- and three-particle interactions
arXiv:2109.00252 · doi:10.3390/universe7100359
Abstract
In this paper we further elaborate on the Bose-Einstein condensate (BEC) dark matter model extended in our preceding work [Phys. Rev. D 102, 083510 (2020)] by the inclusion of 6th order (or three-particle) repulsive self-interaction term. Herein, our goal is to complete the picture through adding to the model the 4th order repulsive self-interaction. The results of our analysis confirm the following: while in the preceding work the two-phase structure and the possibility of first-order phase transition was established, here we demonstrate that with the two self-interactions involved, the nontrivial phase structure of the enriched model remains intact. For this to hold, we study the conditions which the parameters of the model, including the interaction parameters, should satisfy. As a by-product and in order to provide some illustration, we obtain the rotation curves and the (bipartite) entanglement entropy for the case of particular dwarf galaxy.
