DOI: 10.1038/s41586-026-10762-7 Source: https://www.nature.com/articles/s41586-026-10762-7 期刊信息 Nature: 《自然》,北京大学卢晓波团队报道了扭转菱面体石墨烯中的分数高陈数绝缘体, Wang, Zhang, Xiaobo IssueVolume: 2026-07-15 Abstract: The realization of fractional Chern insulators opens the possibility of exploring fractionally charged excitations1, Zaizhe,14,11 in the absence of a magnetic field. A central question is whether lattice-based systems can give rise to radically new states。

20. Here we investigate a type of moir flat-band system composed of Bernal bilayer graphene and rhombohedral tetralayer graphene. We discover an unprecedented richness of quantum anomalous Hall insulators with Chern numbers from |C|=1 to |C|=7 at a moir filling factor v=1 and around v=3.
