Bernd Binder Soliton Coupling Driven by Phase Fluctuations in Auto-Parametric Resonance (19K, LaTeX 2e) ABSTRACT. In this paper the interaction of sine-Gordon solitons and mediating linear waves is modelled by a special case of auto-parametric resonance, the Rayleigh-type self-excited non-linear autonomous system driven by a statistical phase gradient related to the soliton energy. Spherical symmetry can stimulate "whispering gallery modes" (WGM) with integral coupling number M=137.
