报告题目：Plasma Turbulence and Stochastic Ion Heating

　　报告人：夏倩博士（University of Wisconsin, Madison, USA）

　　摘要：Plasma turbulence at kinetic scales attracts considerable interest due to its importance for solar wind heating, magnetic reconnection, and laboratory experiments. The nature of such turbulence is not well understood. Existing phenomenological models typically address the plasma turbulence either at hydrodynamic scales (larger than the plasma microscales such that the ion gyroscale, inertial scale, acoustic scale), or at small subproton scales. Our current study will bridge the gap between those two distinct regimes. It will address the transition from the strong large-scale Alfven turbulence to small-scale Kinetic-Alfven turbulence. Progress and plans for the other applications will also be discussed in this talk.
