Field-tunable correlated states in H-stacked twisted MoS₂.

Twisted transition metal dichalcogenide bilayers offer a versatile platform for exploring strongly correlated states. Here, we study near H-stacked MoS₂ bilayers that realize a multiorbital Hubbard model. The theoretically predicted ultra-flat moire bands at both the valence and conduction band edges strongly enhance electron correlation effects, observable in excitonic spectra. We study the evolution of these correlations under electric and magnetic fields, demonstrating their robustness and tunability arising from the system's unique layer, valley, and orbital degrees of freedom.
