urn:hdl:2117/99765 Topological dragging of solitons Kartashov, Yaroslav V. Vysloukh, Victor A. Torner Sabata, Lluís Àrees temàtiques de la UPC::Enginyeria de la telecomunicació::Telecomunicació òptica::Fotònica Àrees temàtiques de la UPC::Enginyeria de la telecomunicació::Telecomunicació òptica Photonics Optical communications Fotònica Comunicacions òptiques We put forward properties of solitons supported by optical lattices featuring topological dislocations and show that solitons experience attractive and repulsive forces around the dislocations. Suitable arrangements of dislocations are even found to form soliton traps, and the properties of such solitons are shown to crucially depend on the trap topology. The uncovered phenomenon opens a new concept for soliton control and manipulation, e.g., in disk-shaped Bose-Einstein condensates.
