Understand

A new model describing the dark sector of the universe is established.

The model involves Bose-Einstein condensate (BEC) as dark energy (DE) and an excited state above it as dark matter (DM).
The condensate is assumed to have a negative pressure and is embodied as an exotic fluid with Chaplygin equation of state.
Excitations are described as a quasiparticle gas.
