Haldane and Dimer phases in a frustrated spin chain: an exact groundstate and associated topological phase transition

Shaon Sahoo, Dayasindhu Dey, Sudip Kumar Saha +1

A Heisenberg spin- $s$ chain with alternating ferromagnetic ( $- J_{1}^{F} < 0$ ) and antiferromagnetic ( $J_{1}^{A} > 0$ ) nearest-neighbor (NN) interactions, exhibits the Dimer and spin- $2 s$ Halda…
