论文摘要
最近的理论研究发现，在磁场在拓扑状态上应用磁场时，量子旋转液态状态具有Spinon Fermi表面。我们研究了整个过渡过程中的热厅电导率，描述了间隙状态的量化热霍尔电导率如何变为无质量的无旋转旋钮表面状态下未量化的热霍尔电导率。我们考虑两种情况，两种情况，都是潜在的实验兴趣：在蜂窝晶状体上具有非亚洲伊斯林拓扑秩序的状态，以及三角形晶格上的阿贝尔手性旋转液体拓扑秩序的状态。
Recent theoretical studies have found quantum spin liquid states with spinon Fermi surfaces upon the application of a magnetic field on a gapped state with topological order. We investigate the thermal Hall conductivity across this transition, describing how the quantized thermal Hall conductivity of the gapped state changes to an unquantized thermal Hall conductivity in the gapless spinon Fermi surface state. We consider two cases, both of potential experimental interest: the state with non-Abelian Ising topological order on the honeycomb lattice, and the state with Abelian chiral spin liquid topological order on the triangular lattice.
