Dimerization and N\'eel order in different quantum spin chains through a shared loop representation

The ground states of the spin-$ S $ antiferromagnetic chain $H_\textrm{AF}$ with a projection-based interaction and the spin-$ 1/2$ XXZ-chain $ H_\textrm{XXZ} $ at anisotropy parameter $\Delta=\cosh(\lambda) $ share a common loop representation in terms of a two-dimensional functional integral which is similar to the classical planar $Q...More
