论文摘要
通过结合实验和数值模拟，这些模拟模拟了摇摆原子玻璃体凝结物的动力学，我们揭示了这些系统中量子湍流的惊人性质。与超流体氦文献中描述的涡旋线的缠结不同，我们发现湍流的原子冷凝水包含强烈碎片密度波动的混合物和不均匀分布的小的随机涡流环。这种不寻常的湍流形式具有其自身的性质和缩放行为，我们称为强量子湍流，与在经典或其他量子系统中观察到的湍流显着不同，从而在湍流研究中构成了新的挑战。
By combining experiments and numerical simulations which model the dynamics of shaken atomic Bose-Einstein condensates, we reveal the surprising nature of quantum turbulence in these systems. Unlike the tangles of vortex lines described in the superfluid helium literature, we find that our turbulent atomic condensate contains a mixture of strong fragmented density fluctuations and small random vortex loops which are not homogeneously distributed. This unusual form of turbulence, with its own properties and scaling behaviour, which we call strong quantum turbulence, is significantly different from the turbulence which is observed in either classical or other quantum systems, thus posing a new challenge in turbulence research.
