Strange correlations in spin-1 Heisenberg antiferromagnets by Wierschem, Keola, Sengupta, Pinaki

“…After finding the expected long-range behavior in these two symmetry conserving phases, we go on to verify the topological nature of two-leg and three-leg spin-1 Heisenberg antiferromagnetic ladders. This demonstrates the power of the strange correlator in distinguishing between trivial and nontrivial symmetry protected topological phases.…”
