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

It seems that we should think of the bonds between dots in the image as being like spin 1/2 singlets, ^v-v^. So this wld be s'thing like: *(^v-v^)(^v-v^)*, where the two * states are to be specified. But I don't see how to choose the *s so these are in the right sym. subspacespic.twitter.com/TJQXWnai06

Anyone understand the ground state of AKLT / what I'm missing? @tobiasosborne @AndrewDohertyQu @andrewmchilds @dabacon?

Wow all of those people are way more qualified than I am (esp
@AndrewDohertyQu but he's in stealth startup land and won't answer my DMs!) The ground state is simply take spin 1/2 singlets and then project ends of neighboring singlets onto S=1 states? - 3 more replies
