摘要:

我们报告的实验验证最近预测的集体模式的自旋,稳定的背散射相互作用,在一个模型量子自旋链材料。我们利用K $_2$ CuSO $_4$ Br $_2$中均匀的Dzyaloshinskii-Moriya相互作用的独特几何结构来测量电子自旋共振(ESR)响应双峰的两个分量之间的相互作用诱导的分裂。从这一点,我们直接确定的“边际无关”的自旋之间的背散射相互作用的第一次的大小。

英文摘要:

We report experimental verification of the recently predicted collective modes of spinons, stabilized by backscattering interaction, in a model quantum spin chain material. We exploit the unique geometry of uniform Dzyaloshinskii-Moriya interactions in K$_2$CuSO$_4$Br$_2$ to measure the interaction-induced splitting between the two components of the electron spin resonance (ESR) response doublet. From that we directly determine the magnitude of the "marginally irrelevant" backscattering interaction between spinons for the first time.
