论文摘要
我们已经研究了使用Schwinger-Boson平均场理论(SBMFT)研究了Dzyaloshinskii-Moriya相互作用对Kagome Heisenberg抗铁磁铁的影响。在SBMFT框架内,Messio等人认为,Kagome Antiferromagnet的基态可能是手性拓扑旋转液体(Phys。Phys。Rev.Lett。108,207204(2012))。因此,我们计算了零温度的基态相图,考虑到时间反转状态以及完全对称的Ansätze。我们在实验和其他研究中讨论了这些结果的相关性。最后,我们计算了相关阶段中的静态和动态自旋结构因子。
We have studied the effect of the Dzyaloshinskii-Moriya interaction on kagome Heisenberg anti-ferromagnet using Schwinger boson mean field theory (SBMFT). Within SBMFT framework, Messio et al had argued that the ground state of kagome antiferromagnet is possibly a chiral topological spin liquid (Phys. Rev. Lett. 108, 207204 (2012)). Thus, we have computed zero-temperature ground state phase diagram considering the time-reversal breaking states as well as fully symmetric Ansätze. We discuss the relevance of these results in experiments and other studies. Finally, we have computed the static and dynamic spin structure factors in relevant phases.
