量子化涡旋与量子turbulence

Quantized vortices and quantum turbulence

M. Tsubota, K. Kasamatsu

摘要:

本文综述了原子玻色-爱因斯坦凝聚体中的量子涡旋和量子湍流。他们以前已经在超流氦中研究了很长一段时间。量子湍流是当前低温物理研究的重要课题之一。原子玻色-爱因斯坦凝聚在研究这类问题上有两个明显的优势:量子化涡旋可以直接可视化,相互作用参数可以通过费什巴赫共振控制。一个一般性的介绍,其次是量子化的旋涡,流体动力学不稳定性,和量子湍流在原子玻色-爱因斯坦凝聚体的动力学描述。

英文摘要:

We review recent important topics in quantized vortices and quantum turbulence in atomic Bose--Einstein condensates (BECs). They have previously been studied for a long time in superfluid helium. Quantum turbulence is currently one of the most important topics in low-temperature physics. Atomic BECs have two distinct advantages over liquid helium for investigating such topics: quantized vortices can be directly visualized and the interaction parameters can be controlled by the Feshbach resonance. A general introduction is followed by a description of the dynamics of quantized vortices, hydrodynamic instability, and quantum turbulence in atomic BECs.
