M. Karbach et al., FINITE-SIZE ANALYSIS OF THE STRUCTURE FACTORS IN THE ONE-DIMENSIONAL SPIN-1 2 ANTIFERROMAGNETIC XXZ MODEL/, Physical review. B, Condensed matter, 50(13), 1994, pp. 9281-9292
We perform a finite-size analysis of the longitudinal and transverse s
tructure factors S(j)(p, gamma, N), j = 1, 3 in the ground state of th
e one-dimensional spin-1/2 XXZ model. Comparison with the exact result
s of Tonegawa for the XX model yields excellent agreement.
