论文摘要
$ s = 1 $抗铁磁链的磁化过程，具有单离子各向异性$ d $，并且使用数值对角度研究了。两种相互作用均在磁化过程中稳定了2-MAGNON TOMONAGA-LUTTINGER液体（TLL）相。基于数值对角线计算得出的几个激发差距，介绍了磁化过程的某些相图。这些相图表明，自旋列显性tll阶段出现在较高的磁化下，对于足够大的负$ d $。
The magnetization process of the $S=1$ antiferromagnetic chain with the single-ion anisotropy $D$ and the biquadratic interaction is investigated using the numerical diagonalization. Both interactions stabilize the 2-magnon Tomonaga-Luttinger liquid (TLL) phase in the magnetization process. Based on several excitation gaps calculated by the numerical diagonalization, some phase diagrams of the magnetization process are presented. These phase diagrams reveal that the spin nematic dominant TLL phase appears at higher magnetizations for sufficiently large negative $D$.
