Spontaneous dimerization, critical lines, and short-range correlations in a frustrated spin-1 chain

Natalia Chepiga, Ian Affleck, Frederic Mila

We report on a detailed investigation of the spin-1 $J_{1} - J_{2} - J_{3}$ Heisenberg model, a frustrated model with nearest-neighbor coupling $J_{1}$ , next-nearest neighbor coupling $J_{2}$ , a…

Comment on "Frustration and Multicriticality in the Antiferromagnetic Spin-1 Chain"

Natalia Chepiga, Ian Affleck, Frederic Mila

The phase diagram of the spin-1 chain with bilinear-biquadratic and next-nearest neighbor inter- actions, recently investigated by Pixley, Shashi and Nevidomskyy [Phys. Rev. B 90,…
