内容記述 | We develop our novel model of cosmology based on Bose?Einstein condensation. This model unifies the dark energy and the dark matter, and predicts the multiple collapse of condensation, followed by the final acceleration regime of cosmic expansion. We first explore the generality of this model, especially the constraints on the boson mass and condensation conditions. We further argue the robustness of this model over a wide range of parameters of mass, self-coupling constant and the condensation rate. Then the dynamics of BEC collapse and the preferred scale of the collapse are studied. Finally, we describe possible observational tests of our model, especially the periodicity of the collapses and the gravitational wave associated with them. | |||||
