"Under appropriate conditions, light propagating in nonlinear media exhibitsa remarkable behaviour - the propagation is identical to that of a fluid.Perturbations on the transverse beam profile will propagate as waves in aperfect fluid and in many cases the fluid behaves as a superfluid that can beused to study turbulence, vorticity and other phenomena that are of relevance for superfluids and Bose-Einstein condensates. This project, at theinterface between laser physics, superfluid physics and quantum physics willinvestigate new systems in which to observe photon fluid dynamics and willthen apply these concepts to a variety of problems. Most notably, we have along-standing interest in so-called ""analogue gravity"", i.e. the creation ofhydrodynamical analogues for curved spacetimes that can then be used tomimic and study objects such as (artificial) rotating black holes or (artificial)gravitational waves. This project is strictly experimental"

“在适当的条件下，光在非线性介质中的传播具有显著的特性--传播与流体的传播相同。横向光束轮廓上的扰动将在完美流体中以波的形式传播，在许多情况下，流体表现为超流体，可用于研究湍流、涡度和其他与超流体和玻色-爱因斯坦凝聚相关的现象。这个项目，在激光物理学，超流体物理学和量子物理学之间的接口将研究新的系统，在其中观察光子流体动力学，然后将这些概念应用到各种问题。最值得注意的是，我们一直对所谓的“模拟引力”感兴趣，即为弯曲的时空创造流体动力学模拟物，然后可以用来模拟和研究物体，如（人造）旋转黑洞或（人造）引力波。这个项目是严格的实验”
