Long-range sound-mediated dark-soliton interactions in trapped atomic condensates

Lookup NU author(s): Dr Joy AllenORCiD, Professor Carlo Barenghi, Professor Nikolaos ProukakisORCiD



A long-range soliton interaction is discussed whereby two or more dark solitons interact in an inhomogeneous atomic condensate, modifying their respective dynamics via the exchange of sound waves without ever coming into direct contact. An idealized double-well geometry is shown to yield perfect energy transfer and complete periodic identity reversal of the two solitons. Two experimentally relevant geometries are analyzed which should enable the observation of this long-range interaction.
