First experimental proof of multiscale coupling in plasma has implications for fusion energy

Microscopic turbulence in plasma can trigger macroscopic structural changes. In complex physical systems, such cross-scale interactions—between different spatial and temporal scales—are known as multiscale coupling. To the best of their knowledge, Prof. Yong-Seok Hwang’s team, together with the Asia Pacific Center for Theoretical Physics, has now experimentally proven this phenomenon for the first time.
