论文摘要
在本文中，我们提出了一种源自统计力学形式主义的状态宇宙学方程的通用形式，假设宇宙加速情景可以解释为准粒子系统。通过考虑一种广义的超流体方法，可以通过参数$ s $调制能量谱，就会出现一个状态的负方程，作为与\ textit {exotic} superfluid系统相关的激发。我们表明，对于$ s \ sim 0.293 $，$ w \ simeq-1 $，这可能与$λ$ CDM型号的标准状态方程有关。
In this paper we present a generic form of the cosmological Equation of State derived from the formalism of Statistical Mechanics, assuming that a cosmic acceleration scenario can be interpreted as a system of quasi-particles. By considering a generalised superfluidity approach, in which the energy spectrum can be modulated via a parameter $s$, a negative equation of state arises as excitations associated with an \textit{exotic} superfluid system. We show that for $s\sim 0.293$, $w\simeq-1$, which can be related to the standard equation of state for the $Λ$CDM model.
