Trying to understand the ground state of the AKLT model, and having trouble parsing the paper. Here's how it's described in the famous AKLT paper, and the corresponding Hamiltonian:pic.twitter.com/wv9iEBF1k5

Mike if you want some other refs to subsequent work would recommend Werner and others CMP paper, Gross and others on the correlation space picture. And the whole literature in “SPT” phases which explains the near degeneracies on the line that you were discussing with Miles
Thanks! I might. I entertained myself yesterday by computing the AKLT ground state explicitly in a couple of different forms. It's an interesting model.

There is this amazing point of view on these states where instead of projecting at sites on maximally entangled pairs between sites, you create it as an open system where the “system”, a qubit for AKLT, interacts unitarily with a sequence of “environments”, spin 1s for AKLT

Is this in those papers you mentioned?
