论文摘要
我们开发了一种在相应的Schrödinger运营商的光谱中使用两个或三个共存的光谱奇异性设计复杂电势的方法。用几个示例说明了该方法。此外，我们还提供了一个简单的食谱来通过故意碰撞两个简单的频谱来创建二阶光谱奇点。
We develop an approach for designing complex potentials with two or three coexisting spectral singularities in the spectra of the respective Schrödinger operators. The approach is illustrated with several examples. In addition, we offer a simple recipe to create a second-order spectral singularity by intentionally colliding two simple ones.
