AI 中文摘要
我们研究了量子弹跳球问题中与经典焦散相关的量子干涉和能量现象，将其称为量子焦散。通过考虑初始高斯波包，我们展示了与底层经典轨迹族相关的焦散的存在。我们将焦散附近的相关相位奇点链与基于尖点突变线构建的半经典皮尔斯函数联系起来。我们还量化了这些解中表现出的超能量——局部能量超过最大组成能量本征值的空间区域。我们使用马德隆/玻姆轨迹给出了焦散和超能量行为的补充描述，这为轨迹的能量及其如何穿越相位奇点链提供了额外的见解。
英文摘要
We investigate the quantum interference and energetic phenomena associated with classical caustics in the quantum bouncing ball problem, we refer to as quantum caustics. By considering an initial Gaussian wavepacket, we show that caustics associated with the underlying classical trajectory families are exhibited. We connect the associated phase singularity chains in the vicinity of the caustic with the semiclassical Pearcey function built on the cusp catastrophe lines. We also quantify the amount of superenergy exhibited in these solutions - regions of space where the local energy exceeds the largest constituent energy eigenvalue. We give a complimentary description of the caustic and superenergy behavior using the Madelung/Bohm trajectories, which gives additional insight about the energy of the trajectories and how they traverse the phase singularity chains.
