A global research partnership including scientists from the FAMU-FSU College of Engineering and the National High Magnetic Field Laboratory has unveiled a fundamental universal principle that regulates how minute whirlpools interact, collide, and morph within quantum fluids, which also has consequences for comprehending fluids that adhere to classical physics.

The investigation, published in the Proceedings of the National Academy of Sciences, presented new revelations regarding vortex dynamics in superfluid helium, an extraordinary liquid that showcases zero-resistance flow at temperatures nearing absolute zero. The findings illustrate that when these quantum vortices cross paths and reconnect, they part at a speed greater than their original approach velocity, generating bursts of energy that exemplify turbulence in both quantum and classical fluids.

“Superfluids provide a uniquely transparent view into turbulence,” stated FAMU-FSU College of Engineering Professor Wei Guo, a co-author of the study. “We’re starting to grasp the universal physics that unites quantum and classical realms, and that’s an exhilarating frontier for both science and technology.”
