Non-reciprocal topological solitons in active metamaterials
A local driving mechanism for solitons that accelerates both solitons and antisolitons in the same direction, called non-reciprocal driving, is introduced, showing a subtle interplay between non-reciprocity and topological solitons and providing waveguiding and wave-processing possibilities for other fields.
