标题： Nature of chiral spin liquids on the kagome lattice

摘要： 我们研究了在kagome晶格上的扩展Heisenberg模型中最近发现的手性自旋液体的稳定性和性质。 使用Gutzwiller投影波函数方法——即部分子构造——我们获得了与这些扩展Heisenberg模型的基态的高重叠。 我们进一步建议，在时间反演不变情况下手性自旋液体的出现与两种磁有序相之间的经典转变线有关。 显示英文摘要

摘要： We investigate the stability and the nature of the chiral spin liquids which were recently uncovered in extended Heisenberg models on the kagome lattice. Using a Gutzwiller projected wave function approach -- i.e. a parton construction -- we obtain large overlaps with ground states of these extended Heisenberg models. We further suggest that the appearance of the chiral spin liquid in the time-reversal invariant case is linked to a classical transition line between two magnetically ordered phases.
