Heisenberg model on a space with negative curvature: topological spin textures on the pseudosphere
L. R. A. Belo, N. M. Oliveira-Neto, W. A. Moura-Melo +2
Heisenberg-like spins lying on the pseudosphere (a 2-dimensional infinite space with constant negative curvature) cannot give rise to stable soliton solutions. Only fractional solu…

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…
