| 英文摘要 | Using the density-matrix-renormalization-group technique, we calculate numerically the low-energy excitation spectrum and magnetization curve of the spin-1 antiferromagnetic chain in a staggered magnetic field, which is expected to describe the physics of the R2BaNiO5 (R not equal Y) family below the Neel temperature of the magnetic rare-earth (Rf sublattice. These results are valid in the entire range of the staggered field, and agree with those given by the nonlinear sigma model study for small fields, but differ from the latter for large fields. They are consistent with the available experimental data. The correlation functions for this model are also calculated. The transverse correlations display the anticipated exponential decay with-shorter correlation length, while the: longitudinal correlations show explicitly the induced staggered magnetization.
