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 Heisenberg model, a frustrated model with nearest-neighbor coupling , next-nearest neighbor coupling , 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,…

Dimerization transitions in spin-1 chains
Natalia Chepiga, Ian Affleck, Frederic Mila
We study spontaneous dimerization transitions in a Heisenberg spin-1 chain with additional next-nearest neighbor (NNN) and 3-site interactions using extensive numerical simulations…
