Today's #arXivsummary: https://arxiv.org/abs/2303.16222 by Chern & Castelnovo. Authors subject generic nearest-neighbor spin model of Kitaev magnets to a sufficiently strong in-plane magnetic field. Topologically trivial and nontrivial parameter regimes coexist under in-plane magnetic fields. Topological phase diagrams of the magnon bands studied. #CondMat #StrEl #arXiv_2303_16222
