Abstract
It is shown that the acceleration of the sine-Gordon solitons by a constant torque increases as for small times . For larger times, the velocity behaves like tanh . Thus the soliton dynamical behavior is not Newtonian. Analytical arguments are given based on the linear perturbation theory which generalize this conclusion to any weak external perturbation of sine-Gordon solitons.
