全息术和物质创造再谈
Holography and matter creation revisited
摘要：
本文对单宇宙模型中的全息暗能量方法和物质创生效应进行了研究，并讨论了一些有趣的情况。我们测试这个宇宙学的建议对最近的观测。考虑到自由宇宙学参数的最佳拟合值，该模型表现出从减速宇宙膨胀到加速宇宙膨胀的过渡。对于这类模型，由符合参数不能一致地确定减速-加速转变。在有效水平上，与整个能量密度贡献相关联的参数状态描述了目前流体类比中的精华场景。
英文摘要：
The consideration of the holographic dark energy approach and matter creation effects in a single cosmological model is carried out in this work accordingly, we discuss some cases of interest. We test this cosmological proposal against recent observations. Considering the best fit values obtained for the free cosmological parameters, the model exhibits a transition from a decelerated cosmic expansion to an accelerated one. The deceleration-acceleration transition can not be determined consistently from the coincidence parameter for this kind of model. At effective level the parameter state associated to the whole energy density contribution describes a quintessence scenario in the fluid analogy at present time.
