Turbulence in magnetized high-temperature plasmas, crucial for both natural and laboratory settings, involves complex cross-scale interactions. Here, the authors experimentally uncover nonlinear interactions between micro- and hyper-fine scale fluctuations, revealing a bifurcation that suppresses micro-scale turbulence while amplifying hyper-fine scale turbulence, with significant implications for understanding plasma dynamics.
