论文摘要
在Plakida-tserkovnikov算法之后，建议对真实两次换向器的真实两次换向器的延迟延迟的一块绿色功能。从此结果开始，相应的木元素自能量的低温积分表示是通过截断的外形因子膨胀获得的，但是没有任何重新召集。在建议的方法中，可以很容易地研究横向动力学结构因子的低温渐近物。提出了一些获得的线形。
Dyson equation for the real two-time commutator retarded one-magnon Green function of the ferromagnetically polarized XX chain is suggested following the Plakida-Tserkovnikov algorithm. Starting from this result a low-temperature integral representation for the corresponding magnon self energy is obtained by the truncated form factor expansion however without any resummations. Within the suggested approach the low-temperature asymptotics of the transverse dynamical structure factor may be readily studied. Some obtained line shapes are presented.
