论文摘要
在本文中，我们在爱因斯坦重力中获得了可遍历的虫洞（TW）溶液，并在银河系中具有暗物质的功能形式。暗物质模型是伪等温度，它是从修饰的重力中得出的。对于给定的中央密度，探索了TW的可能性，以确定形状函数。探测模型中的无效能量条件（NEC）和弱能条件。我们还研究了考虑星系中的暗物质光环外，考虑了TWS的存在。一个有趣的观察结果是，即使在标量场的存在下不违反NEC，也存在TW溶液。
In the paper we obtain traversable wormhole (TW) solutions in the Einstein gravity with a functional form of the dark matter in the galactic halo. The dark matter model is pseudo isothermal which is derived from modified gravity. For a given central density the possibility of TW is explored determining the shape functions. The null energy condition (NEC) and the weak energy conditions in the model is probed. We also study the existence of TWs considering homogeneous scalar field in addition to the dark matter halo in the galaxies. An interesting observation is that TW solutions exist even if NEC is not violated in the presence of scalar field.
