Static Structure Factors of the XXZ-Model in the presence of a uniform field
M. Karbach, K. -H. Mütter, M. Schmidt
The static structure factors of the XXZ model in the presence of uniform field are determined from an exact computation of the groundstates at given total spin on rings with $N=4,6…

Looking at the Haldane Conjecture from a Grouptheoretical Point of View
K. -H. Mütter
Based on the Lieb-Schultz-Mattis construction we present a five parameter family of Spin-1 Hamiltonians with degenerate groundstate. Starting from the critical symmetric Ha…

Finite Size Analysis of the Structure Factors in the Antiferromagnetic XXZ Model
M. Karbach, K. -H. Mütter, M. Schmidt
We perform a finite size analysis of the longitudinal and transverse structure factors in the groundstate of the spin- XXZ model. Comparison with th…
