Abstract
Recent advances in both experimental and theoretical research have shed light on the distinct nature of quantum turbulence, especially in contrast to its classical counterpart. In this study, we explore the dynamics of the Gross-Pitaevskii equation within a rotating frame, emphasizing pattern formation and the spontaneous generation of vortex lattices. Our findings reveal that rotating quantum flows exhibit fundamental differences from classical flows, particularly in the self-organization of vortex arrays, and the emergence of anisotropic dissipation mechanisms. These phenomena lead to anomalous scaling exponents, compatible with observations of Vinen turbulence and recent simulations of multi-charged vortices. Finally, we will briefly discuss the impact of rotation on the decaying of the system, identifying a critical transition associated with pattern formation as the rotation rate increases.
