Author(s): Yingxi Bai, Zhiqi Chen, Baibiao Huang, Ying Dai, and Chengwang Niu Achieving intrinsic Chern insulators (CIs) with zero net magnetization remains a long-standing and formidable challenge. Here, motivated by the unique opportunities that topological magnons offer for low-dissipation transport, we propose a general theoretical framework for realizing magnon CIs in fi… [Phys. Rev.
