论文摘要
暗能量是一个难以捉摸的概念，它是在二十年前引入的，目的是使宇宙的加速成为可理解的现象。但是，这种能量的性质远非理解，既不是一种基本和观察方式。在这项工作中，我们研究了颗粒存在的宇宙学后果（在先前的工作中称为``Ewkons'''）是准分区分的，遵守非正统的统计量，并且具有类似于许多存在的暗能量候选者（包括压力密度和能量密度之间的负面关系）的状态方程）。我们找到了这种Ewkon流体的有效标量场描述，并获得了以黑暗能量为主时代的宇宙学解。这可以被视为一类黑暗能源模型。
Dark energy is an elusive concept, which has been introduced two decades ago in order to make the acceleration of the universe a comprehensible phenomenon. However, the nature of this energy is far from being understood, both from a fundamental as well as an observational way. In this work we study cosmological consequences of the existence of particles (which we called ``ewkons'' in a previous work) which are quasi distinguishable, obey unorthodox statistics, and have an equation of state similar to many existent dark energy candidates (including negative relation between pressure and energy density). We find an effective scalar field description of this ewkon fluid, and obtain cosmological solutions for the dark energy dominated epoch. This can be considered as a one-parameter class of dark energy models.
