摘要：

The surface energy of the antiferromagnetic spin-1/2 XXZ Heisenberg chain is derived in the region Delta (-1 from the known Bethe ansatz solution for free boundaries with surface fields. The result gives the surface energy of related models satisfying the Temperley-Lieb algebra. The models discussed are the quantum Q-state Potts chain and a family of isotropic spin-s chains including the spin-1 biquadratic model.
