$Λ$即将推出：参数化冻结字段
$Λ$ is Coming: Parametrizing Freezing Fields
摘要：
我们探讨冻结暗能量，在该领域的演变接近宇宙学常数在晚些时候。我们提出了两个一般的，两个参数的形式来描述类的冻结场模型，在类似的解冻场，在这里基于物理的流动参数或校准的$w$ - $w'$相空间。像距离和哈勃参数这样的可观测量与精确数值解的误差在0.1%以内，而暗能量状态方程的误差一般在1%以内。
英文摘要：
We explore freezing dark energy, where the evolution of the field approaches that of a cosmological constant at late times. We propose two general, two parameter forms to describe the class of freezing field models, in analogy to ones for thawing fields, here based on the physics of the flow parameter or the calibrated $w$-$w'$ phase space. Observables such as distances and Hubble parameters are fit to within 0.1%, and the dark energy equation of state generally to within better than 1%, of the exact numerical solutions.
