It is found that the localization of plastic deformation can be conveniently addressed by invoking a hypothetical quasi-particle conjugated with the wave process of flow localization. The mass of the quasiparticle and the area of its localization have been defined.2 pages, 1 fig. 1 table. Submitted to Phys. Rev. LettersMaterials SciencePattern Formation and Solitonstext
