论文摘要
与持续电流的同轴堆积的环形凝结物相结合，这表明一个有吸引力的物理平台，用于研究与约瑟夫森效应相互作用的各种现象中的各种现象，这在弱相互作用与量子kelvin-helmholtz的弱相互作用方面相关。我们建议使用实验可访问的方法来制备在两个耦合的同轴环原子 - 原子 - 玻色 - 因晶体中具有不同拓扑电荷的状态。我们的结果开辟了直接观察原子玻色子凝结物中旋转约瑟夫森涡流的道路。
Coupled coaxially stacked toroidal condensates with persistent currents suggest an appealing physical platform for the investigation of various phenomena related to interacting superflows from Josephson effects in the regime of weak interactions to the quantum Kelvin-Helmholtz instability for merging rings. We suggest experimentally accessible methods to prepare states with different topological charges in two coupled coaxial ring-shaped atomic Bose-Einstein condensates. Our results open up the way to direct observation of rotational Josephson vortices in atomic Bose-Einstein condensates.
