Transition to the Haldane phase driven by electron-electron correlations
Abstract One of the most famous quantum systems with topological properties, the spin $${{{{{{{\mathcal{S}}}}}}}}=1$$ S = 1 antiferromagnetic Heisenberg chain, is well-known to display exotic $${{{{{{{\mathcal{S}}}}}}}}=1/2$$ S = 1 / 2 edge states. However, this spin model has not been analyzed from...
