尖峰电位与量子滑降
Spiked potentials and quantum toboggans
摘要：
即使量子（准）粒子的运动沿着复平面中的左右对称（PT对称）曲线路径进行，束缚态的谱也可以保持物理性，即，真实的和有界的下面）。我们提出一个概括。首先，我们展示了如何拓扑不平凡（tobogganic）的轮廓可以允许生活在几张黎曼曲面。其次，散射制度的规格制定这样一类模型。
英文摘要：
Even if the motion of a quantum (quasi-)particle proceeds along a left-right-symmetric (PT-symmetric) curved path in complex plane, the spectrum of bound states may remain physical, i.e., real and bounded below). We propose a generalization. Firstly, we show how the topologically less trivial (tobogganic) contours may be allowed to live on several sheets of a Riemann surface. Secondly, the specification of a scattering regime is formulated for such a class of models.
