论文摘要
在本文中，我们考虑了第三个量化的宇宙学模型，其光$ c $的速度不同，而重力常数$ g $都以非微耦合标量字段为代表。这种模型的第三个量化导致双重verse的场景，而两个组件是机械纠缠的。我们计算描述纠缠的两个参数，即：后者似乎是纠缠的适当度量的纠缠的能量和熵。我们认为，纠缠可以表现为一种有效的完美流体，其特征在于时间依赖于压缩指数$ w_ {eff} $，在某些特定情况下，它与宇宙弦的流体相对应。看来，这种纠缠诱发的有效完美液在早期可能会产生明显的倒闭效应。
In this paper we consider a third quantized cosmological model with varying speed of light $c$ and varying gravitational constant $G$ both represented by non-minimally coupled scalar fields. The third quantization of such a model leads to a scenario of the doubleverse with the two components being quantum mechanically entangled. We calculate the two parameters describing the entanglement, namely: the energy and the entropy of entanglement where the latter appears to be a proper measure of the entanglement. We consider a possibility that the entanglement can manifests itself as an effective perfect fluid characterized by the time dependent barotropic index $w_{eff}$, which for some specific case corresponds to the fluid of cosmic strings. It seems that such an entanglement induced effective perfect fluid may generate significant backreaction effect at early times.
