Exact solutions of an Ising spin chain with a spin-1 impurity |
(color online) (a) The dependence of impurity induced energy deformation ΔE(p,x) on the impurity coupling strength Jimp/J. Here we choose λ = hx/J = 2. (b) The dependence of impurity induced energy deformation on the effective magnetic field hx/J. Here x = Jimp/J = 1. |
