Sine-Gordon kinks are a much studied integrable system that possessesmulti-soliton solutions. Recent studies on sine-Gordon kinks withspace-dependent square-well-type potentials have revealed interesting dynamicsof a single kink interacting with wells and barriers. In this paper, we study aclass of smooth space-dependent potentials and discuss the dynamics of one kinkin the presence of different wells. We also present values for the criticalvelocity for different types of barriers. Furthermore, we study two kinksinteracting with various wells and describe interesting trajectories such asdouble-trapping, kink knock-out and double-escape.
