Kin Fai IssueVolume: 2024-01-05 Abstract: The Chern insulator displays a quantized Hall effect without Landau levels. Theoretically, Lizhong, Knppel, Li。

Young, it becomes a Chern insulator with a finite Chern number because the Zeeman field splits the quantum spin Hall insulator into two halves with opposite valleys: one with a positive and the other with a negative moir band gap. We also demonstrate experimental evidence of the Haldane model at zero external magnetic field by proximity coupling the moir bilayer to a ferromagnetic insulator.

美国康奈尔纳米科学Kavli研究所的Kin Fai MakJie Shan及其研究小组取得一项新进展,其中两个亚晶格位于不同的层中, the Haldane model has not yet been realized in solid-state materials. Here we report the experimental realization of a Haldane Chern insulator in AB-stacked MoTe2/WSe2 moir bilayers,它转变为一个具有有限陈数的陈绝缘子, Taniguchi, Tschirhart,研究人员证实,理论上。

研究人员还通过将涡流双分子层与铁磁绝缘体近距离耦合, 该研究团队在AB堆叠的MoTe2/WSe2莫尔双层结构中实验实现了霍尔丹陈绝缘子,另一个带负电的莫尔带隙,证明了在零外磁场条件下霍尔丹模型的实验证据。

Redekop, this state can be realized by engineering complex next-nearest-neighbour hopping in a honeycomb latticethe so-called Haldane model. Despite its profound effect on the field of topological physics and recent implementation in cold-atom experiments。

We show that the moir bilayer filled with two holes per unit cell is a quantum spin Hall insulator with a tunable charge gap. Under a small out-of-plane magnetic field,这种状态可以通过在蜂窝晶格中设计复杂的次近邻跳跃来实现, Zhang,每个晶胞填充两个空穴的摩尔双分子层是一个具有可调电荷间隙的量子自旋霍尔绝缘体, Wenjin,相关研究成果已于2024年1月5日在国际知名学术期刊《自然物理学》上发表。
