We develop our novel model of cosmology based on the Bose-Einstein condensation. This model unifies the Dark Energy and the Dark Matter, and predicts 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 the 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.

Vortex-reconnection energy bounds in Bose-Einstein-condensed and superfluid dark matter halos
Vortex reconnections in BEC/superfluid dark matter halos produce dark-sector heating at a rate that is secular but sub-virial for relaxed non-interacting soliton cores, with the dominant uncertainty being the true vor...

Testing Non-minimally Coupled BEC Dark Matter with Gravitational Waves
Using the 1.7-second delay between GW170817 and its gamma-ray burst, the paper constrains non-minimally coupled BEC dark matter, finding ς ≳ 10⁻²⁵ eV for free oscillations and weaker bounds when oscillations are damped.

A mechanism for formation of Bose-Einstein condensation in cosmology
Cosmic expansion causes the final-state momenta in χχ→φφ scattering to shrink, driving the produced φ particles toward a Bose-Einstein condensate.
