More than eighty years ago Hans Bethe predicted that elementary spin waves, known as magnons, in onedimensional
quantum magnets can form bound states - i.e. that two magnons can pair up and propogate
together. Identifying signatures of magnon bound states has so far remained the subject of intense theoretical
research, and their detection has proved challenging for experiments.

Solitary waves that maintain their shape as they propagate, known as solitons, occur in many physical
systems, from water waves, to light pulses to quantum mechanical matter waves in superfluids and
superconductors. Solitons are highly nonlinear and localized, properties which make them very sensitive
probes of the medium in which they propagate.
