论文摘要
最近,提倡一个常规黑洞的新型模型,该模型具有通过Misner-Sharp Quasi-local质量的指数抑制(在核心区域)实现的渐近Minkowski核心。我们将使用这个常规的黑洞作为模板,使用“剪切和粘贴”技术构建一个球形对称的薄壳可穿越的虫洞,从而构建了另一个黑洞模仿。计算虫孔喉咙处的表面应力 - 能量,并分析虫孔的稳定性。一个重要的结果是(与他们的Schwarzschild薄壳对应物相比),通过增加抑制参数“ A”来增加对Misner-sharp准分局部质量质量的指数抑制,这也大大增加了这些薄壳孔的稳定性区域,并增加了这些薄壳孔的稳定区域,并使能量造成的能力造成的含量较小,以使ersoty的含量造成极大的损害。
Recently, a novel model for a regular black hole was advocated which possesses an asymptotically Minkowski core implemented via an exponential suppression (in the core region) of the Misner-Sharp quasi-local mass. Using this regular black hole as a template, we shall construct a spherically symmetric thin-shell traversable wormhole using the "cut-and-paste" technique, thereby constructing yet another black hole mimicker. The surface stress-energy at the wormhole throat is calculated, and the stability of the wormhole is analyzed. An important result is that, (as compared to their Schwarzschild thin-shell counterparts), increasing the exponential suppression of the Misner-Sharp quasi-local mass by increasing the suppression parameter "a", also considerably increases the stability regions for these thin-shell wormholes, and furthermore minimizes the amount of energy condition violating exotic matter required to keep the wormhole throat open.
