Theory of Correlated Insulators and Superconductor at $\nu =1$ in Twisted WSe${}_2$

The observation of a superconducting phase, an intertwined insulating phase, and a continuous transition between the two at a commensurate filling of $\nu =1$ in bilayers of twisted WSe${}_2$ at $\theta ={3.65}^0$ raises a number of intriguing questions about the origin of this phenomenology. Here we report the possibility of a displacement-field induced continuous transition between a superconductor and a quantum spin-liquid Mott insulator at $\nu =1$, starting with a simplified three-orbital model of twisted WSe${}_2$, including on-site, nearest-neighbor density-density interactions, and a chiral-exchange interaction, respectively. By employing parton mean-field theory, we discuss the nature of these correlated insulators, their expected evolution with the displacement-field, and their phenomenological properties.
