Research Abstract

The project was organized for the purpose of constructing analytical theories of nonlinear wave phenomena involving soliton-like excitations in real plasmas, and of dynamical processes of non-ideal solitons which do not preserve their identities under the influence of perturbations. A kinetic theory of solitons has been initiated under the co-operation among experimental, numerical and theoretical physicists, and applied mathematicians. The main results are following: 1. Solitons emitted in the course of the development of a beam-plasma instability were found to stabilize the instability. Emission of solitons is also turned out to play a cricial role for a transition from an unstable to stable equilibrium in the system of the Sine-Gordon equation. 2. Both theoretical and experimental studies of soliton reflection in a plasma seath were made to show a good agreement and give a clear interpretation of the mechanism. 3. Soliton processes in plasmas with negative ions were studied to reveal the effect of higher-order nonlinearity. 4. Propagation characteristics of large amplitude solitons in an inhomogeneous plasma were numerically examined. Theoretical works were started on nonlinear processes such as soliton propagation in a medium of multi-layered structures and under a complicated configuration of magnetic fields which certainly cannot be treated by conventional perturbation theories. 5. Numerical simulations on nonlinear processes in plasmas were performed to quantitatively analyze relationship between a build-up of dissipative structure and energy relaxation, mechanisms of the collapse of a large amplitude high frequency wave, and of particle acceleration by large amplitude waves. 6. Mathematical theories of exact solution methods were consolidated: several outcomes are a discovery of soliton-like pulse solutions in a nonlinear dissipative system, constitution of solutions to the Toda molecule equation and derivation of new soliton equations.
