Fig. 5: Chiral solitons.
a The pristine spin chain with uniform clockwise vector handedness. Dimers are marked by colored backgrounds to differentiate between the alternating species that make up the uniform spin chain. b By flipping both spins in a dimer it transforms into the other species and two chiral solitons are created. This process is slightly gapped due to the presence of interchain coupling in LiCuVO4. c By exchanging two neighboring dimers the soliton can move through the spin chain without creating additional changes in its handedness. Based on ref. 8.
