    Stable particles in anisotropic spin-1 chains

    Motivated by field-theoretic predictions we investigate the stable excitations that exist in two characteristic gapped phases of a spin-1 model with Ising-like and single-ion anisotropies. The sine-Gordon the...

    On \(\mathsf{c = 1}\) critical phases in anisotropic spin-1 chains

    Quantum spin-1 chains may develop massless phases in presence of Ising-like and single-ion anisotropies. We have studied c = 1 critical phases by means of both analytical techniques, including a map** of the la...

    Multiparticle continuum in the excitation spectrum of the compound CsNiCl

    Recent neutron scattering experiments on CsNiCl3 reveal some features that are not well described by the standard nonlinear σ model, nor by numerical simulations, for isolated S = 1 spin chains. In particular, i...
