The 1-soliton solutions can be visualized with the use of the elastic ribbon sine-Gordon model introduced by Julio Rubinstein in 1970. Here we take a clockwise (left-handed) twist of the elastic ribbon to be a kink with topological charge θ θ K = − − 1 . The alternative counterclockwise (right-handed) twist with topological charge θ θ AK = + 1 will be an antikink.
