论文摘要
我们研究了无质量标量波在几何形状中的吸收,该几何形状与施瓦茨柴尔德溶液之间的插值和属于莫里斯 - thorne溶液类别的蠕虫孔之间的吸收。在插值分支的中间,该几何形状描述了一个常规的黑洞。我们使用部分波方法来计算此几何形状中的标量吸收横截面。我们的结果表明,黑洞和虫洞具有独特的吸收光谱。例如,我们得出的结论是,虫洞的结果的特征是存在quasibound状态,这些状态在吸收光谱中产生了Breit-Wigner样共振。
We study the absorption of massless scalar waves in a geometry that interpolates between the Schwarzschild solution and a wormhole that belongs to the Morris-Thorne class of solutions. In the middle of the interpolation branch, this geometry describes a regular black hole. We use the partial wave approach to compute the scalar absorption cross section in this geometry. Our results show that black holes and wormholes present distinctive absorption spectra. We conclude, for instance, that the wormhole results are characterized by the existence of quasibound states which generate Breit-Wigner-like resonances in the absorption spectrum.
