Combinatorial point for higher spin loop models
P. Zinn-justin · 2007
Integrable loop models associated with higher representations (spin ℓ/2) of Uq(sl(2)) are investigated at the point q = −e ±iπ/(ℓ+2). The ground state eigenvalue and eigenvectors are described. Introducing inhomogeneities into the models allows to derive a sum rule for the ground state entries.
