论文摘要
由于最近对壳拓扑中超低量子气体的实验实现的动机，我们提出了对壳形的玻璃玻璃体冷凝物的物质波透镜技术的直接实现。这种方法允许在其自由膨胀过程中显着扩展冷凝水壳的观察时间，并可以研究新型的量子多体对弯曲几何影响的影响。通过分析和数值方法，我们得出了逼真的镜头方案的最佳参数，以节省数百毫秒的时间。
Motivated by the recent experimental realization of ultracold quantum gases in shell topology, we propose a straightforward implementation of matter-wave lensing techniques for shell-shaped Bose-Einstein condensates. This approach allows to significantly extend the observation time of the condensate shell during its free expansion and enables the study of novel quantum many-body effects on curved geometries. With both analytical and numerical methods we derive optimal parameters for realistic lensing schemes to conserve the shell shape of the condensate for times up to hundreds of milliseconds.
