论文摘要
我们对J. Phys发表评论。 Soc。 JPN。 Masaki-Kato等人的91，024001（2022）。并表明他们的结果与在硬核极限的Bose-Hubbard模型的半经典自旋波近似非常吻合。这允许恢复S波散射长度和Lee-huang-yang校正的分析公式。
We comment on J. Phys. Soc. Jpn. 91, 024001 (2022) by Masaki-Kato et al. and show that their results are in very good agreement with the semi-classical spin-wave approximation of Bose-Hubbard model in the hardcore limit. This allows for recovering the analytical formulae for both the s-wave scattering length and the Lee-Huang-Yang correction.
