Elementary Excitations in Quantum Antiferromagnetic Chains: Dyons, Spinons and Breathers
arXiv:cond-mat/0201298
Abstract
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.
