"Quasi-particle breakdown" in the quasi-one-dimensional Ising ferromagnet CoNb$_2$O$_6$
We present experimental and theoretical evidence that an interesting quantum many-body effect -- quasi-particle breakdown -- occurs in the quasi-one-dimensional spin-1/2 Ising-like ferromagnet CoNb$_2$O$_6$ in its paramagnetic phase at high transverse field as a result of explicit breaking of spin i...
