... solution represents a large amplitude defect which satisfies the boundary condition △ ( L / 2 ) = − △ ( -L / 2 ) . It is natural to look for similar large amplitude defects where the order parameter does not change sign . Such states ...

... solution = 0 there are two solutions π Ꮎ = 2 π for n - n = 0 and 0 = for n - n + = 1. The + 4 former corresponds to a well - separated kink - antikink pair and does not represent a new type of defect . The latter is the polaron solution ...
