Abstract
In this chapter, we present the physics of nonlinear wave-particle interactions that lead to the electron kappa velocity distribution function as a stationary asymptotic state. The theoretical framework is based upon the plasma weak turbulence theory, which does not invoke nonextensive thermodynamics at all, but the final solution shows that the kappa distribution is the only allowable state in a weakly turbulent plasma. This finding implicates a profound interrelationship between the turbulent equilibrium state in plasmas and the nonextensive thermodynamic description.
