摘要：

Using the Jordan-Wigner fermionization in two dimensions we obtain the zz wave vector- and frequency-dependent structure factor for the spin-1/2 isotropic XY model on a spatially anisotropic square lattice. We use the obtained results to discuss a role of the interchain interaction for the dynamic properties of quasi-one-dimensional systems. (C) 2003 Elsevier B.V. All rights reserved.
