Abstract:
A percussion on particles moving in a uniform magnetic field induces a distribution of charges in a plasma. The accrued charge tensor qik(x,t), which is the electric charge that has passed from t=0 to t through the unit area normal to xi due to a percussion of unit strength exerted in the xk direction at x=0 and t=0, is computed. The tensor qik is equivalent to the space-time polarization response of plasma electrodynamics. In this derivation, neither the Vlasov equation nor Fourier-Laplace transforms are employed. As an application, a priori bounds (i.e., independent of the distribution functions and of Laplace transforms) for the growth in time of plane-wave modes of a magnetized plasma are obtained by an operational method. The connection of the impulsion with statistical theoretical concepts is also noted. The fluctuation-dissipation theorem is given in a classical-physics version and it is found that the correlator of microscopic currents for noninteracting particles jijkx,t0 of a nonequilibrium plasma is related to qik through (/t)qik =(/E)jijkx,t0. © 1987 The American Physical Society.
