标题： Traversable Wormholes supported by Holographic Dark Energy with a modified Equation of State

摘要： 受全息暗能量模型的启发，我们考虑不同的能量密度分布作为获得可穿越虫洞解的可能来源。 由于这些能量密度都是正的，我们必须引入一个形式为$p_{r}% (r)=\omega_{r}\left( r\right) \rho(r)$的状态方程。 我们将发现，在函数$\omega_{r}\left( r\right) $对$r\rightarrow\infty$发散的情况下，可以施加零潮汐力。 为了克服这种不便，我们放弃要求零潮汐力，通过在函数$\omega_{r}\left( r\right) $上引入适当的修改，以在任何地方得到有限的结果。 我们将发现，这样的修改将使状态方程在喉部附近的行为保持不变。 此外，尽管有初始假设，我们将发现每种暗能量分布都会被转移到幻影区域。 在不同的能量密度提案中，只有一种分布不需要对原始$\omega _{r}\left(r\right) $进行修改以获得零潮汐力。 这种能量密度分布将与全局单极子的出现相容。 显示英文摘要

摘要： Inspired by holographic dark energy models, we consider different energy density profiles as possible sources needed to have traversable wormholes solutions. Since such energy densities are all positive, we are forced to introduce an equation of state of the form $p_{r}% (r)=\omega_{r}\left( r\right) \rho(r)$. We will find that Zero Tidal Forces can be imposed at the price of having the function $\omega_{r}\left( r\right) $ divergent for $r\rightarrow\infty$. To overcome this inconvenient, we abandon the request of having Zero Tidal Forces, by introducing appropriate modifications on the function $\omega_{r}\left( r\right) $ in such a way to obtain a finite result everywhere. We will find that such modifications will leave the behavior of the Equation of State close to the throat invariant. Moreover, despite of the initial assumption, we will find that every dark energy profile will be moved into the phantom region. Among the different energy density proposals, only one profile will not require a modification of the original $\omega _{r}\left(r\right) $ to have Zero Tidal Forces. Such an energy density profile will be consistent with the appearance of a Global Monopole.
