Phys.org  March 15, 2023 In macroscopic quantum condensates the quasiclassical turbulent dynamics at large scales is altered at small scales, where the quantization of vorticity is essential. The nature of this transition remains an unanswered question. An international team of researchers (Finland, UK, Israel) expanded the concept of wave-driven turbulence to rotating quantum fluids where the spectrum of waves extends to microscopic scales as Kelvin waves on quantized vortices. They excited inertial waves at the largest scale by periodic modulation of the angular velocity and observed dissipation-independent transfer of energy to smaller scales and the eventual onset of the elusive […]
