论文摘要
我们考虑在最近提出的{\ it Pole pole pole pole polet Dark Energy}模型中，我们考虑到通货膨胀，辐射和物质主导的时代和物质的可穿越虫洞几何形状的演变。我们表明，不断发展的辐射和物质主导的虫洞空间满足了无效的能量状况（NEC），但在后期具有负能量密度，从而违反了该特定域中的弱能量条件（WEC）。但是，我们以一个具体的例子证明，由共同不变的无质量领域支撑的无可观EMT不断发展的虫洞原则上可以满足WEC，因此可以始终和NEC始终和径向坐标的所有值满足NEC。因此，人们可能会想象一种情况，即这些几何形状通过量子引力过程源于普朗克时代。然后，通货膨胀可以为这些普朗克虫洞的扩大提供自然机制，在这些虫洞中，它们的FLRW背景进化受极点黑能的控制。在文献中首次提出了特定的动态$ 4 $维解决方案，可以满足各处的NEC和WEC。
We consider the evolution of traversable wormhole geometries in the inflationary, radiation -- and matter -- dominated eras, and dynamic wormholes with a traceless energy-momentum tensor (EMT), within the recently proposed {\it pole dark energy} model. We show that the evolving radiation -- and matter -- dominated wormhole spacetimes satisfy the null energy condition (NEC), but possess negative energy densities at late times, thus violating the weak energy condition (WEC) in this specific domain. However, we demonstrate with a specific example that the traceless EMT evolving wormholes, supported by conformally invariant massless fields, in principle, could satisfy the WEC, and consequently the NEC, at all times and for all values of the radial coordinate. Thus, one may imagine a scenario in which these geometries originate in the Planckian era through quantum gravitational processes. Inflation could then provide a natural mechanism for the enlargement of these Planckian wormholes, where their FLRW background evolution is governed by pole dark energy. For the first time in the literature, specific dynamical $4$-dimensional solutions are presented that satisfy the NEC and WEC everywhere and everywhen.
