Physics of Alfven Waves

       Liu Chen

Abstract

Alfvén  waves discovered by Hannes Alfvén (1942 Nature 150405) are fundamental electromagnetic oscillations prevalent in magnetically confined plasmas existing in the nature and laboratories. Alfvén  waves play important roles in the heating, stability, and transport of magnetized plasmas. The anisotropic nearly incompressible shear Alfvén wave is particularly interesting since, due to inhomogeneities and geometries in realistic plasmas, its wave spectra consist of both the regular discrete and the singular continuous components. In this talk, I will discuss interesting features of the spectral properties of Alfvén  waves, spontaneous wave excitations via resonance with energetic particles, and nonlinear physics issues dealing with both wave-particle as well as wave-wave interactions. Examples from both space and laboratory plasmas will be used to illustrate the underlying physics.
