"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，在非线性介质中传播的光表现出显着的行为 - 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，并且在许多情况下，流体表现为可以使用的超流体研究与超流体和玻色爱因斯坦凝聚相关的湍流、涡旋和其他现象。该项目位于激光物理学、超流体物理学和量子物理学之间。将研究观察光子流体动力学的新系统，然后将这些概念应用于各种问题。最值得注意的是，我们一直对所谓的“模拟重力”感兴趣，即为弯曲时空创建流体动力学类似物。然后可以用于模拟和研究诸如（人造）旋转黑洞或（人造）引力波之类的物体，该项目是严格的实验性项目。
