伊夫·库德、伊曼纽尔·福特和同事们最近发现，在振动液浴表面持续存在的毫米液滴可能会通过与自身波场的共振相互作用自我推进。我们回顾了实验证据，表明行走的液滴表现出以前被认为是微观量子领域独有的某些特征。然后，我们回顾了这种流体动力导航波系统的理论描述，从而深入了解其量子样行为的起源。量子化源于液滴的导波场对其施加的动态约束，而多模态统计似乎是混沌导波动力学的一个特征。我们试图评估这种流体动力系统作为量子模拟的潜力和局限性。这种流体系统与量子导波理论进行了比较，表明它与波米力学明显不同，与德布罗意的量子动力学的原始概念、他的双解理论以及随机电动力学中相对较近的扩展更密切相关。
Yves Couder, Emmanuel Fort and coworkers have recently discovered that a millimetric droplet sustained on the surface of a vibrating fluid bath may self-propel through a resonant interaction with its own wave field. We review experimental evidence indicating that the walking droplets exhibit certain features previously thought to be exclusive to the microscopic, quantum realm. We then review theoretical descriptions of this hydrodynamic pilot-wave system that yield insight into the origins of its quantum-like behavior. Quantization arises from the dynamic constraint imposed on the droplet by its pilot-wave field, while multimodal statistics appear to be a feature of chaotic pilot-wave dynamics. We attempt to assess the potential and limitations of this hydrodynamic system as a quantum analog. This fluid system is compared to quantum pilot-wave theories, shown to be markedly different from Bohmian mechanics, more closely related to de Broglie’s original conception of quantum dynamics, his double-solution theory, and its relatively recent extensions through workers in stochastic electrodynamics.
