Elementary excitations in quantum antiferromagnetic chains: Dyons, spinons and breathers
Considering experimental results obtained on three prototype compounds, TMMC, CsCoCl3 (or CsCoBr3), and Cu Benzoate, we discuss the importance of non-linear excitations in the physics of quantum (and classical) antiferromagnetic spin chains.
