含有自相互作用玻色-爱因斯坦气体的宇宙的加速膨胀

Accelerated expansion of a universe containing a self-interacting Bose-Einstein gas

German Izquierdo, Jaime Besprosvany

摘要:

宇宙的加速度是从一个非相对论性粒子模型中得到的,该模型具有短程吸引相互作用,在足够低的温度下产生玻色-爱因斯坦凝聚体。条件推导出负压行为。特别是,我们表明,幻影加速制度在宇宙的开始解决了视界问题,一致的核合成。

英文摘要:

Acceleration of the universe is obtained from a model of non-relativistic particles with a short-range attractive interaction, at low enough temperature to produce a Bose-Einstein condensate. Conditions are derived for negative-pressure behavior. In particular, we show that a phantom-accelerated regime at the beginning of the universe solves the horizon problem, consistently with nucleosynthesis.
