Multisoliton Dynamics in the Sine-Gordon Model with Two Point Impurities

Collective variables method is used to derive a set of differential equations to describe the dynamics of a kink in the sine-Gordon model with two identical point impurities taking damping into account. It is shown that the scenarios of kink interaction with the waves localized on the impurities, fo...
