Manipulating Individual Topological Solitons and Bisolitons in an Electronic System.

ABSTRACT: While localized topological modes in quantum materials, such as topological solitons and Majorana fermions, promise loss-less delivery of classical and quantum information, manipulating individual topological modes has been highly challenging. The manipulation of Z₄ topological solitons is reported in a 1D charge density wave (CDW) insulator of indium atomic wires on a silicon surface. Using the current injection from a scanning tunneling microscopy tip, individual defects-pinned solitons can be created, translated, and annihilated. Moreover, this method is applied to induce bi-soliton processes such as transforming a soliton into a different soliton, fissioning one into two solitons, and fusing and dissociating two solitons, where soliton topological charges are manipulated.
