Abstract

The excitation spectra of the T=0 dynamic structure factors for the spin, dimer, and trimer fluctuation operators as well as for the newly defined center fluctuation operator in the one-dimensional S=1 Heisenberg model wi th isotropic bilinear (Jcosθ) and biquadratic (Jsinθ) exchange are investigated via the recursion method for systems with up to N=18 site s over the predicted range, -π/4
