报告摘要: Turbulence and magnetic fields are ubiquitous in the universe and participate in a variety of astrophysical processes. On one hand, turbulence can amplify magnetic fields and accounts for the magnetization of astrophysical media via the turbulent dynamo process. On the other hand, magnetic reconnection can generate turbulence, and the turbulent reconnection leads to efficient energy dissipation in strongly magnetized astrophysical systems. A proper understanding of the physics of magnetohydrodynamic (MHD) turbulence is important for studying its interaction with energetic particles, which is a critical ingredient of the study on high-energy astrophysical processes. I will first introduce some important properties of MHD turbulence and then further discuss the effect of MHD turbulence on the diffusion and acceleration of energetic particles, including cosmic rays, and the implications on the observations of e.g., gamma-ray bursts, pulsar wind nebulae.
