在这篇文章中，我们将提供非局域相互作用的确凿证据，同时研究波通过两个狄拉克三角势的反射和传输。特别是，我们将证明波的传输比局域情况下的衰减要小，这是因为非局域性削弱了相互作用的事实。结果，回声被放大了。在引力波的背景下，这些特征可能是潜在的可检测到的，在引力波的背景下，两个狄拉克三角势可以模拟超致密物体表面和光子球处的两个势垒，或者在虫洞的两个光子球处经历非局部相互作用。
In this paper we will provide smoking-gun signatures of nonlocal interactions while studying reflection and transmission of waves bouncing through two Dirac delta potentials. In particular, we will show that the transmission of waves is less damped compared to the local case, due to the fact that nonlocality weakens the interaction. As a consequence the echoes are amplified. These signatures can be potentially detectable in the context of gravitational waves, where two Dirac delta potentials can mimic the two potential barriers at the surface and at the photon sphere of an ultra compact object, or, at the two photon spheres of a wormhole, experiencing nonlocal interactions.
