论文摘要
已知封闭量子流体电路中的涡度以持续电流的形式产生。在这项工作中，我们开发了一种方法，以在实验可访问的方案中在密度耦合的环原子 - 原子 - 因子凝结物之间进行量化涡度的运输。我们在环之间引入了可调的弱环节，我们观察并表征了电流的可控制周期转移，并研究了温度通过一系列互补的最新数值方法来抑制这些振荡的作用。我们的设置为局部加速和旋转的精确度量铺平了道路。
Vorticity in closed quantum fluid circuits is known to arise in the form of persistent currents. In this work, we develop a method to engineer transport of the quantized vorticity between density-coupled ring-shaped atomic Bose-Einstein condensates in experimentally accessible regimes. Introducing a tunable weak link between the rings, we observe and characterize the controllable periodic transfer of the current and investigate the role of temperature on suppressing these oscillations via a range of complementary state-of-the-art numerical methods. Our setup paves the way for precision measurements of local acceleration and rotation.
