Research paperExperimental CharacterizationStoner instabilities and Ising excitonic states in twisted transition metal dichalcogenidesAugusto Ghiotto, LingNan Wei, Larry Song, Jiawei Zang et al.2025·10.48550/arxiv.2405.17316·arXiv:2405.17316AbstractMoiré transition metal dichalcogenide (TMD) systems provide a tunable platform for studying electron-correlation driven quantum phases. In this work, magnetotransport measurements on twisted WSe₂ reveal correlated electronic phases away from commensurability. The first is an antiferromagnetic metal driven by proximity to the van Hove singularity. The second is a re-entrant magnetic-field-driven insulator formed from a small and equal density of electrons and holes with opposite spin projections, interpreted as an Ising excitonic insulator.Read more
