摘要：

Dynamics of sine-Gordon solitons and bions under constant electric field are investigated numerically and interesting phenomenon of dissociation of bions into soliton-antisoliton pair is observed. The feature of the bion dissociation depends on the initial phase of the bion and the electric field. For intermediate strength of the electric field, there are cases that the bion dissociates into two pairs of solitons and antisolitons. In strong field, the equation changes gradually into linear differential equation with random modulation. A possible explanation based on the bion dissociation is proposed for the interpretation of the non-ohmic conductivity observed in TTF-TCNQ at lowest temperature. © 1979, THE PHYSICAL SOCIETY OF JAPAN.
