Quantum fluid Research
He II, the superfluid phase of Helium-4, exhibits fascinating quantum hydrodynamics that have substantial implications for both scientific research and engineering applications. However, progress in this area is impeded by the lack of precise flow measurement tools. Our main goal is to pioneer the development of cutting-edge flow visualization techniques to unlock the full potential of He II and enable groundbreaking discoveries and practical applications in diverse fields.
