Turbulent cascades in superfluid Flatland

该项目旨在通过将许多微小的漩涡（漩涡）搅拌成超流体玻色-爱因斯坦凝聚体来回答湍流中的开放性问题。它试图确定如何涡旋动力学重新分配能量在超流体中跨越宽的长度尺度，如何湍流引起的不稳定性，以及如何湍流重新分配能量在多组分超流体。该项目的成果将阐明量子和经典流体之间的联系，并提供在现实世界系统中的理论模型的明确测试。这些结果将有助于理解量子超流体的物理学，并将为利用捕获的超流体介质进行精确传感的量子增强设备的工程提供信息。

This project aims to answer open questions in turbulence by stirring many tiny whirlpools (vortices) into a superfluid Bose-Einstein condensate. It seeks to determine how vortex dynamics redistribute energy across broad length scales in superfluids, how turbulence arises from instabilities, and how turbulence redistributes energy in multicomponent superfluids. The outcomes of this project will elucidate the links between quantum and classical fluids, and provide unambiguous tests of theoretical models in real-world systems. These results will be beneficial to the understanding of the physics of quantum superfluids, and will inform the engineering of quantum-enhanced devices that utilise trapped superfluid media for precision sensing.
