Introduction . With the development of information technology, it has become crucial to process vast amount of information dispationlessly1 , 2 , 3. In this aspect, topological solitons in one dimensional electronic systems or non-topological solitons in optical fibers have obvious merits as an information carrier since they are highly mobile with immunity against scatterings4 , 5. Moreover, beyond typical Z 2 topological solitons with digital information, recent expe...
