Let $S$ be the spin of the AKLT model, let $\left|SG\right\rangle$ denote its ground state, and define the spin-$2S$ magnon creation operator by … The exact tower of states is … fo…

Let $\{\left|S_{2N}\right\rangle\}$ be the tower of exact states of the spin-1 AKLT model, with energy $E=2N$ and system size $L$. Consider states at finite energy density…
