Quasi-1D magnetic insulators are very attractive for searching and studying quantum many-body phenomena. Here the authors report the four-spinon excitations in quasi-1D spin-chain cuprate Sr2CuO3 by momentum resolved RIXS technique which provides a new route for the creation of magnetic excitations in 1D materials.
