Abstract
A spectrum of fully developed turbulence via subcritical excitation in an inhomogeneous plasma is obtained. The dressed-test-mode analysis is developed, in which a dielectric tensor containing renormalized transfer rates is solved. The energy spectrum of the form E(k⊥) ∝ G0k⊥−3 is obtained in the energy-containing region. (G0 denotes the driving, which is the product of the gradients of plasma pressure and magnetic field.) Turbulent kinetic energy, W ∝ G02, and transport coefficient, χT ∝ G03/2, are found to be nonlinear functions of G0, which presents a typical example of nonlinear, nonequilibrium transport.
