Today's #arXivsummary: https://arxiv.org/abs/2303.12833 by Castro et. al. Authors predict new interacting electronic orders emerging near higher-order Van Hove singularities present in the Chern bands of the Haldane model. Singularities are classified, revealing regimes of ferromagnetism, density-waves, and superconductivity. Repulsive interactions stabilize long-sought PDW state; exotic Chern supermetal possible in which a non-Fermi liquid phase with an anomalous quantum Hall response realized. #CondMat #StrEl #arXiv_2303_12833
