Sine-Gordon kink dynamics in the presence of external fields

The main cause of the prevalent confusion over the nature of sine-Gordon solitons is found to be the particular choice of initial scattering states. With the help of different initial conditions the dynamics of the sG kink is obtained using the linear perturbation technique. This justifies the newto...

Summary:The main cause of the prevalent confusion over the nature of sine-Gordon solitons is found to be the particular choice of initial scattering states. With the help of different initial conditions the dynamics of the sG kink is obtained using the linear perturbation technique. This justifies the newtonian particle behaviour in the appropriate limit.
