Research paperExperimental CharacterizationObservation of two-component exciton condensates in an excitonic insulatorRuishi Qi, Qize Li, Jiahui Nie, Ruichen Xia et al.2025·10.1038/s41563-025-02334-3·arXiv:2603.15443AbstractEvidence of two-component exciton Bose-Einstein condensates in MoSe₂/hBN/WSe₂ electron-hole bilayers is reported by probing spin susceptibility with magneto-optical spectroscopy in a dilution refrigerator. The work identifies three exciton-condensate phases with distinct flavor polarizations and a temperature scale up to about 1.8 K.Read more
