论文摘要
杂叶型过渡金属二北元化（TMDC）Moiré系统提供了一个理想的框架，以研究密切相关的物理学。在这里，我们从理论上研究了MoiréTMDC中激子的骨气多体阶段。通过使用两个Moiré模型和簇平均场理论，我们揭示，由于非本地库仑相互作用，Moiré激子可以具有异国情调的超氧相位，即破裂的翻译不变性的超氟和相关的绝缘状态。相关阶段存在于实验可访问的温度下，并且可以通过扭角和激子密度调节。
Heterobilayer transition metal dichalcogenide (TMDC) moiré systems provide an ideal framework to investigate strongly correlated physics. Here we theoretically study bosonic many-body phases of excitons in moiré TMDCs. By using two moiré models and cluster mean-field theory, we reveal that, due to non-local Coulomb interactions, moiré excitons can feature exotic supersolid phases, i.e. superfluids of broken translational invariance, and correlated insulating states. The correlated phases exist at experimentally accessible temperatures and are tunable via the twist angle and exciton density.
