From confined spinons to emergent fermions: Observation of elementary magnetic excitations in a transverse-field Ising chain

Zhe Wang, Jianda Wu, Shenglong Xu +11

We report on spectroscopy study of elementary magnetic excitations in an Ising-like antiferromagnetic chain compound SrCo${}_2$V${}_2$O${}_8$ as a function of temperature and applied tra…
