Stable particles in anisotropic spin-1 chains
L. Campos Venuti, C. Degli Esposti Boschi, E. Ercolessi +4
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 aniso…

Long-distance entanglement in spin systems
L. Campos Venuti, C. Degli Esposti Boschi, M. Roncaglia
Most quantum system with short-ranged interactions show a fast decay of entanglement with the distance. In this Letter, we focus on the peculiarity of some systems to distribute en…
