超流Chaobergin气体对暗能量和暗物质的统一

Dark Energy and Dark Matter unification via superfluid Chaplygin gas

V. A. Popov

摘要:

建立了一个描述宇宙暗区的新模型。该模型涉及玻色-爱因斯坦凝聚体(BEC)作为暗能量(DE)和其上方的激发态作为暗物质(DM)。假设凝析油为负压流体,并采用Chaubergin状态方程将其转化为奇异流体。激发被描述为准粒子气体。它表明,该模型是不同意与目前的宇宙加速观测。该模型预言了在遥远的将来,有效宇宙学常数将增大,物质将完全消失。

英文摘要:

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. It is shown that the model is not in disagreement with the current observations of the cosmic acceleration. The model predicts increase of the effective cosmological constant and a complete disappearance of the matter at the far future.
