Abstract:
The ground-states of the spin-S antiferromagnetic chain H-AF with a projection-based interaction and the spin-1/2 XXZ-chain H-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-state Potts model at root Q = 2S + 1 ...More
