| contents | The observation of a superconducting phase, an intertwined insulating phase, and a continuous transition between the two at a commensurate filling of $ν=1$ in bilayers of twisted WSe$_2$ at $θ=3.65^0$ 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 $ν=1$, 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. |
