基于Hartree-Fock方法和多标度方法,我们考察了具有格点各向异性的一维铁磁链中的量子孤子和内禀局域模,量子磁振子的波函数由量子包络孤子来描述.在布里渊区边界,量子包络孤子变成了量子内禀局域模,它的量子本征频率在简谐波带的顶部上方,量子磁振子主要集中在中心位置j=j0的附近.

Based on the Hartree-Fock approach and the multiple-scale method, we investigate quantum solitons and intrinsic localized modes in a one-dimensional ferromagnetic chain with on-site anisotropy. The wave function of the quantum magnon is described by the quantum envelope soliton. At the boundary of the Brillouin zone, the quantum envelope soliton becomes the quantum intrinsic localized mode, its quantum eigenfrequency is above the top of the harmonic wave band, the quantum magnons converge mainly on the vicinity at the central site j = j0.
