论文摘要
使用截短的形式膨胀研究磁化$ xx $链的横向动力学结构因子的低温渐近渐近造物进行了研究。与前面的论文不同，我们不使用相应的磁敏感性来使用结构因子的表示。这使得可以在较小和负频率下获得正确的结果。
Using the truncated form factor expansion the low-temperature asymptotics for the transverse dynamical structure factor of the magnetically polarized $XX$ chain is studied. Unlike the previous paper we do not use the representation of structure factor in terms of the corresponding magnetic susceptibility. This enables to obtain correct results at small and negative frequencies.
